+# Juice ![](https://i.imgur.com/jN8Ht.gif)
+
+Given HTML, juice will inline your CSS properties into the `style` attribute.
+
+[Some projects using Juice](PROJECTS.md)
+
+## How to use
+
+Juice has a number of functions based on whether you want to process a file, HTML string, or a cheerio document, and whether you want juice to automatically get remote stylesheets, scripts and image dataURIs to inline.
+
+To inline HTML without getting remote resources, using default options:
+
+```js
+var juice = require('juice');
+var result = juice("<style>div{color:red;}</style><div/>");
+```
+
+result will be:
+```html
+<div style="color: red;"></div>
+```
+
+[Try out the web client version](https://automattic.github.io/juice/)
+
+## What is this useful for ?
+
+- HTML emails. For a comprehensive list of supported selectors see [here](https://www.campaignmonitor.com/css/)
+- Embedding HTML in 3rd-party websites.
+
+## Documentation
+
+Juice is exposed as a standard module, and from CLI with a smaller set of options.
+
+### Options
+
+All juice methods take an options object that can contain any of these properties, though not every method uses all of these:
+
+* `applyAttributesTableElements` - whether to create attributes for styles in `juice.styleToAttribute` on elements set in `juice.tableElements`. Defaults to `true`.
+
+* `applyHeightAttributes` - whether to use any CSS pixel heights to create `height` attributes on elements set in `juice.heightElements`. Defaults to `true`.
+
+* `applyStyleTags` - whether to inline styles in `<style></style>` Defaults to `true`.
+
+* `applyWidthAttributes` - whether to use any CSS pixel widths to create `width` attributes on elements set in `juice.widthElements`. Defaults to `true`.
+
+* `extraCss` - extra css to apply to the file. Defaults to `""`.
+
+* `insertPreservedExtraCss` - whether to insert into the document any preserved `@media` or `@font-face` content from `extraCss` when using `preserveMediaQueries`, `preserveFontFaces` or `preserveKeyFrames`. When `true` order of preference to append the `<style>` element is into `head`, then `body`, then at the end of the document. When a `string` the value is treated as a CSS/jQuery/cheerio selector, and when found, the `<style>` tag will be appended to the end of the first match. Defaults to `true`.
+
+* `inlinePseudoElements` - Whether to insert pseudo elements (`::before` and `::after`) as `<span>` into the DOM. *Note*: Inserting pseudo elements will modify the DOM and may conflict with CSS selectors elsewhere on the page (e.g., `:last-child`).
+
+* `preserveFontFaces` - preserves all `@font-face` within `<style></style>` tags as a refinement when `removeStyleTags` is `true`. Other styles are removed. Defaults to `true`.
+
+* `preserveImportant` - preserves `!important` in values. Defaults to `false`.
+
+* `preserveMediaQueries` - preserves all media queries (and contained styles) within `<style></style>` tags as a refinement when `removeStyleTags` is `true`. Other styles are removed. Defaults to `true`.
+
+* `preserveKeyFrames` - preserves all key frames within `<style></style>` tags as a refinement when `removeStyleTags` is `true`. Other styles are removed. Defaults to `true`.
+
+* `preservePseudos` - preserves all rules containing pseudo selectors defined in `ignoredPseudos` within `<style></style>` tags as a refinement when `removeStyleTags` is `true`. Other styles are removed. Defaults to `true`.
+
+* `removeStyleTags` - whether to remove the original `<style></style>` tags after (possibly) inlining the css from them. Defaults to `true`.
+
+* `webResources` - An options object that will be passed to [web-resource-inliner](https://www.npmjs.com/package/web-resource-inliner) for juice functions that will get remote resources (`juiceResources` and `juiceFile`). Defaults to `{}`.
+
+* `xmlMode` - whether to output XML/XHTML with all tags closed. Note that the input *must* also be valid XML/XHTML or you will get undesirable results. Defaults to `false`.
+
+
+### Methods
+
+#### juice(html [, options])
+
+Returns string containing inlined HTML. Does not fetch remote resources.
+
+ * `html` - html string, accepts complete documents as well as fragments
+ * `options` - optional, see Options above
+
+#### juice.juiceResources(html, options, callback)
+
+Callback returns string containing inlined HTML. Fetches remote resources.
+
+ * `html` - html string
+ * `options` - see Options above
+ * `callback(err, html)`
+   - `err` - `Error` object or `null`
+   - `html` - inlined HTML
+
+#### juice.juiceFile(filePath, options, callback)
+
+Callback returns string containing inlined HTML. Fetches remote resources.
+
+ * `filePath` - path to the html file to be juiced
+ * `options` - see Options above
+ * `callback(err, html)`
+   - `err` - `Error` object or `null`
+   - `html` - inlined HTML
+
+#### juice.juiceDocument($ [, options])
+
+This takes a cheerio instance and performs inlining in-place.  Returns the
+same cheerio instance.  Does not fetch remote resources.
+
+ * `$` - a cheerio instance, be sure to use the same cheerio version that juice uses
+ * `options` - optional, see Options above`
+
+#### juice.inlineContent(html, css [, options])
+
+This takes html and css and returns new html with the provided css inlined.
+It does not look at `<style>` or `<link rel="stylesheet">` elements at all.
+
+ * `html` - html string
+ * `css` - css string
+ * `options` - optional, see Options above
+
+#### juice.inlineDocument($, css [, options])
+
+Given a cheerio instance and css, this modifies the cheerio instance so that the provided css is inlined. It does not look at `<style>` or `<link rel="stylesheet">` elements at all.
+
+ * `$` - a cheerio instance, be sure to use the same cheerio version that juice uses
+ * `css` - css string
+ * `options` - optional, see Options above
+
+### Global settings
+
+#### juice.codeBlocks
+
+An object where each value has a `start` and `end` to specify fenced code blocks that should be ignored during parsing and inlining. For example, Handlebars (hbs) templates are `juice.codeBlocks.HBS = {start: '{{', end: '}}'}`. `codeBlocks` can fix problems where otherwise juice might interpret code like `<=` as HTML, when it is meant to be template language code. Note that `codeBlocks` is a dictionary which can contain many different code blocks, so don't do `juice.codeBlocks = {...}` do `juice.codeBlocks.myBlock = {...}`
+
+#### juice.ignoredPseudos
+
+Array of ignored pseudo-selectors such as 'hover' and 'active'.
+
+#### juice.widthElements
+
+Array of HTML elements that can receive `width` attributes.
+
+#### juice.heightElements
+
+Array of HTML elements that can receive `height` attributes.
+
+#### juice.styleToAttribute
+
+Object of style property names (key) to their respective attribute names (value).
+
+#### juice.tableElements
+
+Array of table HTML elements that can receive attributes defined in `juice.styleToAttribute`.
+
+#### juice.nonVisualElements
+
+Array of elements that will not have styles inlined because they are not intended to render.
+
+#### juiceClient.excludedProperties
+
+Array of css properties that won't be inlined.
+
+### Special markup
+
+#### data-embed
+When a `data-embed` attribute is present on a stylesheet `<link>` that has been inlined into the document as a `<style></style>` tag by the web-resource-inliner juice will not inline the styles and will not remove the `<style></style>` tags.
+
+This can be used to embed email client support hacks that rely on css selectors into your email templates.
+
+### CLI Options
+
+To use Juice from CLI, run `juice [options] input.html output.html`
+
+For a listing of all available options, just type `juice -h`.
+
+> Note that if you want to just type `juice` from the command line, you should `npm install juice -g` so it is globally available.
+
+CLI Options:
+
+The CLI should have all the above [options](#options) with the names changed from camel case to hyphen-delimited, so for example `extraCss` becomes `extra-css` and `webResources.scripts` becomes `web-resources-scripts`.
+
+These are additional options not included in the standard `juice` options listed above:
+
+- `--css [filepath]` will load and inject CSS into `extraCss`.
+- `--options-file [filepath]` will load and inject options from a JSON file. Options from the CLI will be given priority over options in the file when there is a conflict.
+- `codeBlocks` is optionally supported in the options file if you include it. This will allow you to support different template languages in a build process.
+
+### Running Juice in the Browser
+
+Attempting to Browserify `require('juice')` fails because portions of Juice and its dependencies interact with the file system using the standard `require('fs')`. However, you can `require('juice/client')` via Browserify which has support for `juiceDocument`, `inlineDocument`, and `inlineContent`, but not `juiceFile`, `juiceResources`, or `inlineExternal`. *Note that automated tests are not running in the browser yet.*

+
+CSS selector engine supporting jQuery selectors, based on [`css-select`](https://github.com/fb55/css-select).
+
+Supports all jQuery positional pseudo-selectors:
+
+-   `:first`
+-   `:last`
+-   `:eq`
+-   `:nth`
+-   `:gt`
+-   `:lt`
+-   `:even`
+-   `:odd`
+-   `:not(:positional)`, where `:positional` is any of the above.
+
+This library is a thin wrapper around [`css-select`](https://github.com/fb55/css-select).
+Only use this module if you will actually use jQuery positional selectors.

+//=> <html><head></head><body><h2 class="title welcome">Hello there!</h2></body></html>

+
+## Note
+
+We are currently working on the 1.0.0 release of cheerio on the `main` branch. The source code for the last published version, `0.22.0`, can be found [here](https://github.com/cheeriojs/cheerio/tree/aa90399c9c02f12432bfff97b8f1c7d8ece7c307).
+
+## Installation
+
+`npm install cheerio`
+
+## Features
+
+**&#10084; Familiar syntax:**
+Cheerio implements a subset of core jQuery. Cheerio removes all the DOM inconsistencies and browser cruft from the jQuery library, revealing its truly gorgeous API.
+
+**&#991; Blazingly fast:**
+Cheerio works with a very simple, consistent DOM model. As a result parsing, manipulating, and rendering are incredibly efficient.
+
+**&#10049; Incredibly flexible:**
+Cheerio wraps around [parse5](https://github.com/inikulin/parse5) parser and can optionally use @FB55's forgiving [htmlparser2](https://github.com/fb55/htmlparser2/). Cheerio can parse nearly any HTML or XML document.
+
+## Cheerio is not a web browser
+
+Cheerio parses markup and provides an API for traversing/manipulating the resulting data structure. It does not interpret the result as a web browser does. Specifically, it does _not_ produce a visual rendering, apply CSS, load external resources, or execute JavaScript. This makes Cheerio **much, much faster than other solutions**. If your use case requires any of this functionality, you should consider projects like [Puppeteer](https://github.com/puppeteer/puppeteer) or [JSDom](https://github.com/jsdom/jsdom).
+
+## API
+
+### Markup example we'll be using:
+
+```html
+<ul id="fruits">
+  <li class="apple">Apple</li>
+  <li class="orange">Orange</li>
+  <li class="pear">Pear</li>
+</ul>
+```
+
+This is the HTML markup we will be using in all of the API examples.
+
+### Loading
+
+First you need to load in the HTML. This step in jQuery is implicit, since jQuery operates on the one, baked-in DOM. With Cheerio, we need to pass in the HTML document.
+
+This is the _preferred_ method:
+
+```js
+// ES6 or TypeScript:
+import * as cheerio from 'cheerio';
+
+// In other environments:
+const cheerio = require('cheerio');
+
+const $ = cheerio.load('<ul id="fruits">...</ul>');
+
+$.html();
+//=> <html><head></head><body><ul id="fruits">...</ul></body></html>
+```
+
+Similar to web browser contexts, `load` will introduce `<html>`, `<head>`, and `<body>` elements if they are not already present. You can set `load`'s third argument to `false` to disable this.
+
+```js
+const $ = cheerio.load('<ul id="fruits">...</ul>', null, false);
+
+$.html();
+//=> '<ul id="fruits">...</ul>'
+```
+
+Optionally, you can also load in the HTML by passing the string as the context:
+
+```js
+$('ul', '<ul id="fruits">...</ul>');
+```
+
+Or as the root:
+
+```js
+$('li', 'ul', '<ul id="fruits">...</ul>');
+```
+
+If you need to modify parsing options for XML input, you may pass an extra
+object to `.load()`:
+
+```js
+const $ = cheerio.load('<ul id="fruits">...</ul>', {
+  xml: {
+    normalizeWhitespace: true,
+  },
+});
+```
+
+The options in the `xml` object are taken directly from [htmlparser2](https://github.com/fb55/htmlparser2/wiki/Parser-options), therefore any options that can be used in `htmlparser2` are valid in cheerio as well. When `xml` is set, the default options are:
+
+```js
+{
+    xmlMode: true,
+    decodeEntities: true, // Decode HTML entities.
+    withStartIndices: false, // Add a `startIndex` property to nodes.
+    withEndIndices: false, // Add an `endIndex` property to nodes.
+}
+```
+
+For a full list of options and their effects, see [domhandler](https://github.com/fb55/DomHandler) and
+[htmlparser2's options](https://github.com/fb55/htmlparser2/wiki/Parser-options).
+
+Some users may wish to parse markup with the `htmlparser2` library, and
+traverse/manipulate the resulting structure with Cheerio. This may be the case
+for those upgrading from pre-1.0 releases of Cheerio (which relied on
+`htmlparser2`), for those dealing with invalid markup (because `htmlparser2` is
+more forgiving), or for those operating in performance-critical situations
+(because `htmlparser2` may be faster in some cases). Note that "more forgiving"
+means `htmlparser2` has error-correcting mechanisms that aren't always a match
+for the standards observed by web browsers. This behavior may be useful when
+parsing non-HTML content.
+
+To support these cases, `load` also accepts a `htmlparser2`-compatible data
+structure as its first argument. Users may install `htmlparser2`, use it to
+parse input, and pass the result to `load`:
+
+```js
+// Usage as of htmlparser2 version 6:
+const htmlparser2 = require('htmlparser2');
+const dom = htmlparser2.parseDocument(document, options);
+
+const $ = cheerio.load(dom);
+```
+
+### Selectors
+
+Cheerio's selector implementation is nearly identical to jQuery's, so the API is very similar.
+
+#### \$( selector, [context], [root] )
+
+`selector` searches within the `context` scope which searches within the `root` scope. `selector` and `context` can be a string expression, DOM Element, array of DOM elements, or cheerio object. `root` is typically the HTML document string.
+
+This selector method is the starting point for traversing and manipulating the document. Like jQuery, it's the primary method for selecting elements in the document.
+
+```js
+$('.apple', '#fruits').text();
+//=> Apple
+
+$('ul .pear').attr('class');
+//=> pear
+
+$('li[class=orange]').html();
+//=> Orange
+```
+
+##### XML Namespaces
+
+You can select with XML Namespaces but [due to the CSS specification](https://www.w3.org/TR/2011/REC-css3-selectors-20110929/#attribute-selectors), the colon (`:`) needs to be escaped for the selector to be valid.
+
+```js
+$('[xml\\:id="main"');
+```
+
+### Rendering
+
+When you're ready to render the document, you can call the `html` method on the "root" selection:
+
+```js
+$.root().html();
+//=>  <html>
+//      <head></head>
+//      <body>
+//        <ul id="fruits">
+//          <li class="apple">Apple</li>
+//          <li class="orange">Orange</li>
+//          <li class="pear">Pear</li>
+//        </ul>
+//      </body>
+//    </html>
+```
+
+If you want to render the [`outerHTML`](https://developer.mozilla.org/en-US/docs/Web/API/Element/outerHTML) of a selection, you can use the `html` utility functon:
+
+```js
+cheerio.html($('.pear'));
+//=> <li class="pear">Pear</li>
+```
+
+By default, `html` will leave some tags open. Sometimes you may instead want to render a valid XML document. For example, you might parse the following XML snippet:
+
+```js
+const $ = cheerio.load(
+  '<media:thumbnail url="http://www.foo.com/keyframe.jpg" width="75" height="50" time="12:05:01.123"/>'
+);
+```
+
+... and later want to render to XML. To do this, you can use the 'xml' utility function:
+
+```js
+$.xml();
+//=> <media:thumbnail url="http://www.foo.com/keyframe.jpg" width="75" height="50" time="12:05:01.123"/>
+```
+
+You may also render the text content of a Cheerio object using the `text` static method:
+
+```js
+const $ = cheerio.load('This is <em>content</em>.');
+cheerio.text($('body'));
+//=> This is content.
+```
+
+### Plugins
+
+Once you have loaded a document, you may extend the prototype or the equivalent `fn` property with custom plugin methods:
+
+```js
+const $ = cheerio.load('<html><body>Hello, <b>world</b>!</body></html>');
+$.prototype.logHtml = function () {
+  console.log(this.html());
+};
+
+$('body').logHtml(); // logs "Hello, <b>world</b>!" to the console
+```
+
+If you're using TypeScript, you should also add a type definition for your new method:
+
+```ts
+declare module 'cheerio' {
+  interface Cheerio<T> {
+    logHtml(this: Cheerio<T>): void;
+  }
+}
+```
+
+### The "DOM Node" object
+
+Cheerio collections are made up of objects that bear some resemblance to [browser-based DOM nodes](https://developer.mozilla.org/en-US/docs/Web/API/Node). You can expect them to define the following properties:
+
+- `tagName`
+- `parentNode`
+- `previousSibling`
+- `nextSibling`
+- `nodeValue`
+- `firstChild`
+- `childNodes`
+- `lastChild`

+## Special Thanks
+
+This library stands on the shoulders of some incredible developers. A special thanks to:
+
+**&#8226; @FB55 for node-htmlparser2 & CSSSelect:**
+Felix has a knack for writing speedy parsing engines. He completely re-wrote both @tautologistic's `node-htmlparser` and @harry's `node-soupselect` from the ground up, making both of them much faster and more flexible. Cheerio would not be possible without his foundational work
+
+**&#8226; @jQuery team for jQuery:**
+The core API is the best of its class and despite dealing with all the browser inconsistencies the code base is extremely clean and easy to follow. Much of cheerio's implementation and documentation is from jQuery. Thanks guys.
+
+**&#8226; @visionmedia:**
+The style, the structure, the open-source"-ness" of this library comes from studying TJ's style and using many of his libraries. This dude consistently pumps out high-quality libraries and has always been more than willing to help or answer questions. You rock TJ.

+## [5.0.0] (2020-03-14)
+
+### Added
+
+* support for nested commands with action-handlers ([#1] [#764] [#1149])
+* `.addCommand()` for adding a separately configured command ([#764] [#1149])
+* allow a non-executable to be set as the default command ([#742] [#1149])
+* implicit help command when there are subcommands (previously only if executables) ([#1149])
+* customise implicit help command with `.addHelpCommand()` ([#1149])
+* display error message for unknown subcommand, by default ([#432] [#1088] [#1149])
+* display help for missing subcommand, by default ([#1088] [#1149])
+* combined short options as single argument may include boolean flags and value flag and value (e.g. `-a -b -p 80` can be written as `-abp80`) ([#1145])
+* `.parseOption()` includes short flag and long flag expansions ([#1145])
+* `.helpInformation()` returns help text as a string, previously a private routine ([#1169])
+* `.parse()` implicitly uses `process.argv` if arguments not specified ([#1172])
+* optionally specify where `.parse()` arguments "from", if not following node conventions ([#512] [#1172])
+* suggest help option along with unknown command error ([#1179])
+* TypeScript definition for `commands` property of `Command` ([#1184])
+* export `program` property ([#1195])
+* `createCommand` factory method to simplify subclassing ([#1191])
+
+### Fixed
+
+* preserve argument order in subcommands ([#508] [#962] [#1138])
+* do not emit `command:*` for executable subcommands ([#809] [#1149])
+* action handler called whether or not there are non-option arguments ([#1062] [#1149])
+* combining option short flag and value in single argument now works for subcommands ([#1145])
+* only add implicit help command when it will not conflict with other uses of argument ([#1153] [#1149])
+* implicit help command works with command aliases ([#948] [#1149])
+* options are validated whether or not there is an action handler ([#1149])
+
+### Changed
+
+* *Breaking* `.args` contains command arguments with just recognised options removed ([#1032] [#1138])
+* *Breaking* display error if required argument for command is missing ([#995] [#1149])
+* tighten TypeScript definition of custom option processing function passed to `.option()` ([#1119])
+* *Breaking* `.allowUnknownOption()` ([#802] [#1138])
+  * unknown options included in arguments passed to command action handler
+  * unknown options included in `.args`
+* only recognised option short flags and long flags are expanded (e.g. `-ab` or `--foo=bar`) ([#1145])
+* *Breaking* `.parseOptions()` ([#1138])
+  * `args` in returned result renamed `operands` and does not include anything after first unknown option
+  * `unknown` in returned result has arguments after first unknown option including operands, not just options and values
+* *Breaking* `.on('command:*', callback)` and other command events passed (changed) results from `.parseOptions`, i.e. operands and unknown  ([#1138])
+* refactor Option from prototype to class ([#1133])
+* refactor Command from prototype to class ([#1159])
+* changes to error handling ([#1165])
+  * throw for author error, not just display message
+  * preflight for variadic error
+  * add tips to missing subcommand executable
+* TypeScript fluent return types changed to be more subclass friendly, return `this` rather than `Command` ([#1180])
+* `.parseAsync` returns `Promise<this>` to be consistent with `.parse()` ([#1180])
+* update dependencies
+
+### Removed
+
+* removed EventEmitter from TypeScript definition for Command, eliminating implicit peer dependency on `@types/node` ([#1146])
+* removed private function `normalize` (the functionality has been integrated into `parseOptions`) ([#1145])
+* `parseExpectedArgs` is now private ([#1149])
+
+### Migration Tips
+
+If you use `.on('command:*')` or more complicated tests to detect an unrecognised subcommand, you may be able to delete the code and rely on the default behaviour.
+
+If you use `program.args` or more complicated tests to detect a missing subcommand, you may be able to delete the code and rely on the default behaviour.
+
+If you use `.command('*')` to add a default command, you may be be able to switch to `isDefault:true` with a named command.
+
+If you want to continue combining short options with optional values as though they were boolean flags, set `combineFlagAndOptionalValue(false)`
+to expand `-fb` to `-f -b` rather than `-f b`.

+* removed deprecated `customFds` option from call to `child_process.spawn` ([#1052])
+* rework TypeScript declarations to bring all types into imported namespace ([#1081])
+
+### Migration Tips
+
+#### Testing for no arguments
+
+If you were previously using code like:
+
+```js
+if (!program.args.length) ...
+```
+
+a partial replacement is:
+
+```js
+if (program.rawArgs.length < 3) ...
+```

+
+## Installation
+
+```bash
+npm install commander
+```
+
+## Declaring _program_ variable
+
+Commander exports a global object which is convenient for quick programs.
+This is used in the examples in this README for brevity.
+
+```js
+const { program } = require('commander');
+program.version('0.0.1');
+```
+
+For larger programs which may use commander in multiple ways, including unit testing, it is better to create a local Command object to use.
+
+```js
+const { Command } = require('commander');
+const program = new Command();
+program.version('0.0.1');
+```
+
+## Options
+
+Options are defined with the `.option()` method, also serving as documentation for the options. Each option can have a short flag (single character) and a long name, separated by a comma or space or vertical bar ('|').
+
+The options can be accessed as properties on the Command object. Multi-word options such as "--template-engine" are camel-cased, becoming `program.templateEngine` etc. See also optional new behaviour to [avoid name clashes](#avoiding-option-name-clashes).
+
+Multiple short flags may optionally be combined in a single argument following the dash: boolean flags, followed by a single option taking a value (possibly followed by the value).
+For example `-a -b -p 80` may be written as `-ab -p80` or even `-abp80`.
+
+You can use `--` to indicate the end of the options, and any remaining arguments will be used without being interpreted.
+
+Options on the command line are not positional, and can be specified before or after other arguments.
+
+### Common option types, boolean and value
+
+The two most used option types are a boolean option, and an option which takes its value
+from the following argument (declared with angle brackets like `--expect <value>`). Both are `undefined` unless specified on command line.  
+
+Example file: [options-common.js](./examples/options-common.js)
+
+```js
+program
+  .option('-d, --debug', 'output extra debugging')
+  .option('-s, --small', 'small pizza size')
+  .option('-p, --pizza-type <type>', 'flavour of pizza');
+
+program.parse(process.argv);
+
+if (program.debug) console.log(program.opts());
+console.log('pizza details:');
+if (program.small) console.log('- small pizza size');
+if (program.pizzaType) console.log(`- ${program.pizzaType}`);
+```
+
+```bash
+$ pizza-options -d
+{ debug: true, small: undefined, pizzaType: undefined }
+pizza details:
+$ pizza-options -p
+error: option '-p, --pizza-type <type>' argument missing
+$ pizza-options -ds -p vegetarian
+{ debug: true, small: true, pizzaType: 'vegetarian' }
+pizza details:
+- small pizza size
+- vegetarian
+$ pizza-options --pizza-type=cheese
+pizza details:
+- cheese
+```
+
+`program.parse(arguments)` processes the arguments, leaving any args not consumed by the program options in the `program.args` array.
+
+### Default option value
+
+You can specify a default value for an option which takes a value.
+
+Example file: [options-defaults.js](./examples/options-defaults.js)
+
+```js
+program
+  .option('-c, --cheese <type>', 'add the specified type of cheese', 'blue');
+
+program.parse(process.argv);
+
+console.log(`cheese: ${program.cheese}`);
+```
+
+```bash
+$ pizza-options
+cheese: blue
+$ pizza-options --cheese stilton
+cheese: stilton
+```
+
+### Other option types, negatable boolean and boolean|value
+
+You can define a boolean option long name with a leading `no-` to set the option value to false when used.
+Defined alone this also makes the option true by default.
+
+If you define `--foo` first, adding `--no-foo` does not change the default value from what it would
+otherwise be. You can specify a default boolean value for a boolean option and it can be overridden on command line.
+
+Example file: [options-negatable.js](./examples/options-negatable.js)
+
+```js
+program
+  .option('--no-sauce', 'Remove sauce')
+  .option('--cheese <flavour>', 'cheese flavour', 'mozzarella')
+  .option('--no-cheese', 'plain with no cheese')
+  .parse(process.argv);
+
+const sauceStr = program.sauce ? 'sauce' : 'no sauce';
+const cheeseStr = (program.cheese === false) ? 'no cheese' : `${program.cheese} cheese`;
+console.log(`You ordered a pizza with ${sauceStr} and ${cheeseStr}`);
+```
+
+```bash
+$ pizza-options
+You ordered a pizza with sauce and mozzarella cheese
+$ pizza-options --sauce
+error: unknown option '--sauce'
+$ pizza-options --cheese=blue
+You ordered a pizza with sauce and blue cheese
+$ pizza-options --no-sauce --no-cheese
+You ordered a pizza with no sauce and no cheese
+```
+
+You can specify an option which may be used as a boolean option but may optionally take an option-argument
+(declared with square brackets like `--optional [value]`).
+
+Example file: [options-boolean-or-value.js](./examples/options-boolean-or-value.js)
+
+```js
+program
+  .option('-c, --cheese [type]', 'Add cheese with optional type');
+
+program.parse(process.argv);
+
+if (program.cheese === undefined) console.log('no cheese');
+else if (program.cheese === true) console.log('add cheese');
+else console.log(`add cheese type ${program.cheese}`);
+```
+
+```bash
+$ pizza-options
+no cheese
+$ pizza-options --cheese
+add cheese
+$ pizza-options --cheese mozzarella
+add cheese type mozzarella
+```
+
+For information about possible ambiguous cases, see [options taking varying arguments](./docs/options-taking-varying-arguments.md).
+
+### Custom option processing
+
+You may specify a function to do custom processing of option-arguments. The callback function receives two parameters,
+the user specified option-argument and the previous value for the option. It returns the new value for the option.
+
+This allows you to coerce the option-argument to the desired type, or accumulate values, or do entirely custom processing.
+
+You can optionally specify the default/starting value for the option after the function parameter.
+
+Example file: [options-custom-processing.js](./examples/options-custom-processing.js)
+
+```js
+function myParseInt(value, dummyPrevious) {
+  // parseInt takes a string and an optional radix
+  return parseInt(value);
+}
+
+function increaseVerbosity(dummyValue, previous) {
+  return previous + 1;
+}
+
+function collect(value, previous) {
+  return previous.concat([value]);
+}
+
+function commaSeparatedList(value, dummyPrevious) {
+  return value.split(',');
+}
+
+program
+  .option('-f, --float <number>', 'float argument', parseFloat)
+  .option('-i, --integer <number>', 'integer argument', myParseInt)
+  .option('-v, --verbose', 'verbosity that can be increased', increaseVerbosity, 0)
+  .option('-c, --collect <value>', 'repeatable value', collect, [])
+  .option('-l, --list <items>', 'comma separated list', commaSeparatedList)
+;
+
+program.parse(process.argv);
+
+if (program.float !== undefined) console.log(`float: ${program.float}`);
+if (program.integer !== undefined) console.log(`integer: ${program.integer}`);
+if (program.verbose > 0) console.log(`verbosity: ${program.verbose}`);
+if (program.collect.length > 0) console.log(program.collect);
+if (program.list !== undefined) console.log(program.list);
+```
+
+```bash
+$ custom -f 1e2
+float: 100
+$ custom --integer 2
+integer: 2
+$ custom -v -v -v
+verbose: 3
+$ custom -c a -c b -c c
+[ 'a', 'b', 'c' ]
+$ custom --list x,y,z
+[ 'x', 'y', 'z' ]
+```
+
+### Required option
+
+You may specify a required (mandatory) option using `.requiredOption`. The option must have a value after parsing, usually specified on the command line, or perhaps from a default value (say from environment). The method is otherwise the same as `.option` in format, taking flags and description, and optional default value or custom processing.
+
+Example file: [options-required.js](./examples/options-required.js)
+
+```js
+program
+  .requiredOption('-c, --cheese <type>', 'pizza must have cheese');
+
+program.parse(process.argv);
+```
+
+```bash
+$ pizza
+error: required option '-c, --cheese <type>' not specified
+```
+
+### Variadic option
+
+You may make an option variadic by appending `...` to the value placeholder when declaring the option. On the command line you
+can then specify multiple option-arguments, and the parsed option value will be an array. The extra arguments
+are read until the first argument starting with a dash. The special argument `--` stops option processing entirely. If a value
+is specified in the same argument as the option then no further values are read.
+
+Example file: [options-variadic.js](./examples/options-variadic.js)
+
+```js
+program
+  .option('-n, --number <numbers...>', 'specify numbers')
+  .option('-l, --letter [letters...]', 'specify letters');
+
+program.parse();
+
+console.log('Options: ', program.opts());
+console.log('Remaining arguments: ', program.args);
+```
+
+```bash
+$ collect -n 1 2 3 --letter a b c
+Options:  { number: [ '1', '2', '3' ], letter: [ 'a', 'b', 'c' ] }
+Remaining arguments:  []
+$ collect --letter=A -n80 operand
+Options:  { number: [ '80' ], letter: [ 'A' ] }
+Remaining arguments:  [ 'operand' ]
+$ collect --letter -n 1 -n 2 3 -- operand
+Options:  { number: [ '1', '2', '3' ], letter: true }
+Remaining arguments:  [ 'operand' ]
+```
+
+For information about possible ambiguous cases, see [options taking varying arguments](./docs/options-taking-varying-arguments.md).
+
+### Version option
+
+The optional `version` method adds handling for displaying the command version. The default option flags are `-V` and `--version`, and when present the command prints the version number and exits.
+
+```js
+program.version('0.0.1');
+```
+
+```bash
+$ ./examples/pizza -V
+0.0.1
+```
+
+You may change the flags and description by passing additional parameters to the `version` method, using
+the same syntax for flags as the `option` method.
+
+```js
+program.version('0.0.1', '-v, --vers', 'output the current version');
+```
+
+## Commands
+
+You can specify (sub)commands using `.command()` or `.addCommand()`. There are two ways these can be implemented: using an action handler attached to the command, or as a stand-alone executable file (described in more detail later). The subcommands may be nested ([example](./examples/nestedCommands.js)).
+
+In the first parameter to `.command()` you specify the command name and any command-arguments. The arguments may be `<required>` or `[optional]`, and the last argument may also be `variadic...`.
+
+You can use `.addCommand()` to add an already configured subcommand to the program.
+
+For example:
+
+```js
+// Command implemented using action handler (description is supplied separately to `.command`)
+// Returns new command for configuring.
+program
+  .command('clone <source> [destination]')
+  .description('clone a repository into a newly created directory')
+  .action((source, destination) => {
+    console.log('clone command called');
+  });
+
+// Command implemented using stand-alone executable file (description is second parameter to `.command`)
+// Returns `this` for adding more commands.
+program
+  .command('start <service>', 'start named service')
+  .command('stop [service]', 'stop named service, or all if no name supplied');
+
+// Command prepared separately.
+// Returns `this` for adding more commands.
+program
+  .addCommand(build.makeBuildCommand());
+```
+
+Configuration options can be passed with the call to `.command()` and `.addCommand()`. Specifying `hidden: true` will 
+remove the command from the generated help output. Specifying `isDefault: true` will run the subcommand if no other
+subcommand is specified ([example](./examples/defaultCommand.js)).
+
+### Specify the argument syntax
+
+You use `.arguments` to specify the expected command-arguments for the top-level command, and for subcommands they are usually
+included in the `.command` call. Angled brackets (e.g. `<required>`) indicate required command-arguments.
+Square brackets (e.g. `[optional]`) indicate optional command-arguments.
+You can optionally describe the arguments in the help by supplying a hash as second parameter to `.description()`.
+
+Example file: [env](./examples/env)
+
+```js
+program
+  .version('0.1.0')
+  .arguments('<cmd> [env]')
+  .description('test command', {
+    cmd: 'command to run',
+    env: 'environment to run test in'
+  })
+  .action(function (cmd, env) {
+    console.log('command:', cmd);
+    console.log('environment:', env || 'no environment given');
+  });
+
+program.parse(process.argv);
+```
+
+ The last argument of a command can be variadic, and only the last argument.  To make an argument variadic you
+ append `...` to the argument name. For example:
+
+```js
+const { program } = require('commander');
+
+program
+  .version('0.1.0')
+  .command('rmdir <dir> [otherDirs...]')
+  .action(function (dir, otherDirs) {
+    console.log('rmdir %s', dir);
+    if (otherDirs) {
+      otherDirs.forEach(function (oDir) {
+        console.log('rmdir %s', oDir);
+      });
+    }
+  });
+
+program.parse(process.argv);
+```
+
+The variadic argument is passed to the action handler as an array.
+
+### Action handler (sub)commands
+
+You can add options to a command that uses an action handler.
+The action handler gets passed a parameter for each argument you declared, and one additional argument which is the
+command object itself. This command argument has the values for the command-specific options added as properties.
+
+```js
+const { program } = require('commander');
+
+program
+  .command('rm <dir>')
+  .option('-r, --recursive', 'Remove recursively')
+  .action(function (dir, cmdObj) {
+    console.log('remove ' + dir + (cmdObj.recursive ? ' recursively' : ''))
+  })
+
+program.parse(process.argv)
+```
+
+You may supply an `async` action handler, in which case you call `.parseAsync` rather than `.parse`.
+
+```js
+async function run() { /* code goes here */ }
+
+async function main() {
+  program
+    .command('run')
+    .action(run);
+  await program.parseAsync(process.argv);
+}
+```
+
+A command's options on the command line are validated when the command is used. Any unknown options will be reported as an error.
+
+### Stand-alone executable (sub)commands
+
+When `.command()` is invoked with a description argument, this tells Commander that you're going to use stand-alone executables for subcommands.
+Commander will search the executables in the directory of the entry script (like `./examples/pm`) with the name `program-subcommand`, like `pm-install`, `pm-search`.
+You can specify a custom name with the `executableFile` configuration option.
+
+You handle the options for an executable (sub)command in the executable, and don't declare them at the top-level.
+
+Example file: [pm](./examples/pm)
+
+```js
+program
+  .version('0.1.0')
+  .command('install [name]', 'install one or more packages')
+  .command('search [query]', 'search with optional query')
+  .command('update', 'update installed packages', { executableFile: 'myUpdateSubCommand' })
+  .command('list', 'list packages installed', { isDefault: true });
+
+program.parse(process.argv);
+```
+
+If the program is designed to be installed globally, make sure the executables have proper modes, like `755`.
+
+## Automated help
+
+The help information is auto-generated based on the information commander already knows about your program. The default
+help option is `-h,--help`.
+
+Example file: [pizza](./examples/pizza)
+
+```bash
+$ node ./examples/pizza --help
+Usage: pizza [options]
+
+An application for pizzas ordering
+
+Options:
+  -V, --version        output the version number
+  -p, --peppers        Add peppers
+  -c, --cheese <type>  Add the specified type of cheese (default: "marble")
+  -C, --no-cheese      You do not want any cheese
+  -h, --help           display help for command
+```
+
+A `help` command is added by default if your command has subcommands. It can be used alone, or with a subcommand name to show
+further help for the subcommand. These are effectively the same if the `shell` program has implicit help:
+
+```bash
+shell help
+shell --help
+
+shell help spawn
+shell spawn --help
+```
+
+### Custom help
+
+You can display extra information by listening for "--help".
+
+Example file: [custom-help](./examples/custom-help)
+
+```js
+program
+  .option('-f, --foo', 'enable some foo');
+
+// must be before .parse()
+program.on('--help', () => {
+  console.log('');
+  console.log('Example call:');
+  console.log('  $ custom-help --help');
+});
+```
+
+Yields the following help output:
+
+```Text
+Usage: custom-help [options]
+
+Options:
+  -f, --foo   enable some foo
+  -h, --help  display help for command
+
+Example call:
+  $ custom-help --help
+```
+
+### .usage and .name
+
+These allow you to customise the usage description in the first line of the help. The name is otherwise
+deduced from the (full) program arguments. Given:
+
+```js
+program
+  .name("my-command")
+  .usage("[global options] command")
+```
+
+The help will start with:
+
+```Text
+Usage: my-command [global options] command
+```
+
+### .help(cb)
+
+Output help information and exit immediately. Optional callback cb allows post-processing of help text before it is displayed.
+
+### .outputHelp(cb)
+
+Output help information without exiting.
+Optional callback cb allows post-processing of help text before it is displayed.
+
+### .helpInformation()
+
+Get the command help information as a string for processing or displaying yourself. (The text does not include the custom help
+from `--help` listeners.)
+
+### .helpOption(flags, description)
+
+Override the default help flags and description. Pass false to disable the built-in help option.
+
+```js
+program
+  .helpOption('-e, --HELP', 'read more information');
+```
+
+### .addHelpCommand()
+
+You can explicitly turn on or off the implicit help command with `.addHelpCommand()` and `.addHelpCommand(false)`.
+
+You can both turn on and customise the help command by supplying the name and description:
+
+```js
+program.addHelpCommand('assist [command]', 'show assistance');
+```
+
+## Custom event listeners
+
+You can execute custom actions by listening to command and option events.
+
+```js
+program.on('option:verbose', function () {
+  process.env.VERBOSE = this.verbose;
+});
+
+program.on('command:*', function (operands) {
+  console.error(`error: unknown command '${operands[0]}'`);
+  const availableCommands = program.commands.map(cmd => cmd.name());
+  mySuggestBestMatch(operands[0], availableCommands);
+  process.exitCode = 1;
+});
+```
+
+## Bits and pieces
+
+### .parse() and .parseAsync()
+
+The first argument to `.parse` is the array of strings to parse. You may omit the parameter to implicitly use `process.argv`.
+
+If the arguments follow different conventions than node you can pass a `from` option in the second parameter:
+
+- 'node': default, `argv[0]` is the application and `argv[1]` is the script being run, with user parameters after that
+- 'electron': `argv[1]` varies depending on whether the electron application is packaged
+- 'user': all of the arguments from the user
+
+For example:
+
+```js
+program.parse(process.argv); // Explicit, node conventions
+program.parse(); // Implicit, and auto-detect electron
+program.parse(['-f', 'filename'], { from: 'user' });
+```
+
+### Avoiding option name clashes
+
+The original and default behaviour is that the option values are stored
+as properties on the program, and the action handler is passed a
+command object with the options values stored as properties.
+This is very convenient to code, but the downside is possible clashes with
+existing properties of Command.
+
+There are two new routines to change the behaviour, and the default behaviour may change in the future:
+
+- `storeOptionsAsProperties`: whether to store option values as properties on command object, or store separately (specify false) and access using `.opts()`
+- `passCommandToAction`: whether to pass command to action handler,
+or just the options (specify false)
+
+Example file: [storeOptionsAsProperties-action.js](./examples/storeOptionsAsProperties-action.js)
+
+```js
+program
+  .storeOptionsAsProperties(false)
+  .passCommandToAction(false);
+
+program
+  .name('my-program-name')
+  .option('-n,--name <name>');
+
+program
+  .command('show')
+  .option('-a,--action <action>')
+  .action((options) => {
+    console.log(options.action);
+  });
+
+program.parse(process.argv);
+
+const programOptions = program.opts();
+console.log(programOptions.name);
+```
+
+### TypeScript
+
+The Commander package includes its TypeScript Definition file.
+
+If you use `ts-node` and  stand-alone executable subcommands written as `.ts` files, you need to call your program through node to get the subcommands called correctly. e.g.
+
+```bash
+node -r ts-node/register pm.ts
+```
+
+### createCommand()
+
+This factory function creates a new command. It is exported and may be used instead of using `new`, like:
+
+```js
+const { createCommand } = require('commander');
+const program = createCommand();
+```
+
+`createCommand` is also a method of the Command object, and creates a new command rather than a subcommand. This gets used internally
+when creating subcommands using `.command()`, and you may override it to
+customise the new subcommand (examples using [subclass](./examples/custom-command-class.js) and [function](./examples/custom-command-function.js)).
+
+### Import into ECMAScript Module
+
+Commander is currently a CommonJS package, and the default export can be imported into an ES Module:
+
+```js
+// index.mjs
+import commander from 'commander';
+const program = commander.program;
+const newCommand = new commander.Command();
+```
+
+### Node options such as `--harmony`
+
+You can enable `--harmony` option in two ways:
+
+- Use `#! /usr/bin/env node --harmony` in the subcommands scripts. (Note Windows does not support this pattern.)
+- Use the `--harmony` option when call the command, like `node --harmony examples/pm publish`. The `--harmony` option will be preserved when spawning subcommand process.
+
+### Debugging stand-alone executable subcommands
+
+An executable subcommand is launched as a separate child process.
+
+If you are using the node inspector for [debugging](https://nodejs.org/en/docs/guides/debugging-getting-started/) executable subcommands using `node --inspect` et al,
+the inspector port is incremented by 1 for the spawned subcommand.
+
+If you are using VSCode to debug executable subcommands you need to set the `"autoAttachChildProcesses": true` flag in your launch.json configuration.
+
+### Override exit handling
+
+By default Commander calls `process.exit` when it detects errors, or after displaying the help or version. You can override
+this behaviour and optionally supply a callback. The default override throws a `CommanderError`.
+
+The override callback is passed a `CommanderError` with properties `exitCode` number, `code` string, and `message`. The default override behaviour is to throw the error, except for async handling of executable subcommand completion which carries on. The normal display of error messages or version or help
+is not affected by the override which is called after the display.
+
+```js
+program.exitOverride();
+
+try {
+  program.parse(process.argv);
+} catch (err) {
+  // custom processing...
+}
+```
+
+## Examples
+
+Example file: [deploy](./examples/deploy)
+
+```js
+const { program } = require('commander');
+
+program
+  .version('0.1.0')
+  .option('-C, --chdir <path>', 'change the working directory')
+  .option('-c, --config <path>', 'set config path. defaults to ./deploy.conf')
+  .option('-T, --no-tests', 'ignore test hook');
+
+program
+  .command('setup [env]')
+  .description('run setup commands for all envs')
+  .option("-s, --setup_mode [mode]", "Which setup mode to use")
+  .action(function(env, options){
+    const mode = options.setup_mode || "normal";
+    env = env || 'all';
+    console.log('setup for %s env(s) with %s mode', env, mode);
+  });
+
+program
+  .command('exec <cmd>')
+  .alias('ex')
+  .description('execute the given remote cmd')
+  .option("-e, --exec_mode <mode>", "Which exec mode to use")
+  .action(function(cmd, options){
+    console.log('exec "%s" using %s mode', cmd, options.exec_mode);
+  }).on('--help', function() {
+    console.log('');
+    console.log('Examples:');
+    console.log('');
+    console.log('  $ deploy exec sequential');
+    console.log('  $ deploy exec async');
+  });
+
+program.parse(process.argv);
+```

+
+## Support
+
+The current version of Commander is fully supported on Long Term Support versions of Node, and is likely to work with Node 6 but not tested.
+(For versions of Node below Node 6, use Commander 3.x or 2.x.)
+
+The main forum for free and community support is the project [Issues](https://github.com/tj/commander.js/issues) on GitHub.

+
+A CSS selector compiler and engine
+
+## What?
+
+As a **compiler**, css-select turns CSS selectors into functions that tests if
+elements match them.
+
+As an **engine**, css-select looks through a DOM tree, searching for elements.
+Elements are tested "from the top", similar to how browsers execute CSS
+selectors.
+
+In its default configuration, css-select queries the DOM structure of the
+[`domhandler`](https://github.com/fb55/domhandler) module (also known as
+htmlparser2 DOM). To query alternative DOM structures, see [`Options`](#options)
+below.
+
+**Features:**
+
+-   🔬 Full implementation of CSS3 selectors, as well as most CSS4 selectors
+-   🧪 Partial implementation of jQuery/Sizzle extensions (see
+    [cheerio-select](https://github.com/cheeriojs/cheerio-select) for the
+    remaining selectors)
+-   🧑‍🔬 High test coverage, including the full test suites from Sizzle, Qwery and
+    NWMatcher.
+-   🥼 Reliably great performance
+
+## Why?
+
+Most CSS engines written in JavaScript execute selectors left-to-right. That
+means thet execute every component of the selector in order, from left to right
+_(duh)_. As an example: For the selector `a b`, these engines will first query
+for `a` elements, then search these for `b` elements. (That's the approach of
+eg. [`Sizzle`](https://github.com/jquery/sizzle),
+[`nwmatcher`](https://github.com/dperini/nwmatcher/) and
+[`qwery`](https://github.com/ded/qwery).)
+
+While this works, it has some downsides: Children of `a`s will be checked
+multiple times; first, to check if they are also `a`s, then, for every superior
+`a` once, if they are `b`s. Using
+[Big O notation](http://en.wikipedia.org/wiki/Big_O_notation), that would be
+`O(n^(k+1))`, where `k` is the number of descendant selectors (that's the space
+in the example above).
+
+The far more efficient approach is to first look for `b` elements, then check if
+they have superior `a` elements: Using big O notation again, that would be
+`O(n)`. That's called right-to-left execution.
+
+And that's what css-select does – and why it's quite performant.
+
+## How does it work?
+
+By building a stack of functions.
+
+_Wait, what?_
+
+Okay, so let's suppose we want to compile the selector `a b`, for right-to-left
+execution. We start by _parsing_ the selector. This turns the selector into an
+array of the building blocks. That's what the
+[`css-what`](https://github.com/fb55/css-what) module is for, if you want to
+have a look.
+
+Anyway, after parsing, we end up with an array like this one:
+
+```js
+[
+    { type: "tag", name: "a" },
+    { type: "descendant" },
+    { type: "tag", name: "b" },
+];
+```
+
+(Actually, this array is wrapped in another array, but that's another story,
+involving commas in selectors.)
+
+Now that we know the meaning of every part of the selector, we can compile it.
+That is where things become interesting.
+
+The basic idea is to turn every part of the selector into a function, which
+takes an element as its only argument. The function checks whether a passed
+element matches its part of the selector: If it does, the element is passed to
+the next function representing the next part of the selector. That function does
+the same. If an element is accepted by all parts of the selector, it _matches_
+the selector and double rainbow ALL THE WAY.
+
+As said before, we want to do right-to-left execution with all the big O
+improvements. That means elements are passed from the rightmost part of the
+selector (`b` in our example) to the leftmost (~~which would be `c`~~ of course
+`a`).
+
+For traversals, such as the _descendant_ operating the space between `a` and
+`b`, we walk up the DOM tree, starting from the element passed as argument.
+

+
+## API
+
+```js
+const CSSselect = require("css-select");
+```
+
+**Note:** css-select throws errors when invalid selectors are passed to it.This
+is done to aid with writing css selectors, but can be unexpected when processing
+arbitrary strings.
+
+#### `CSSselect.selectAll(query, elems, options)`
+
+Queries `elems`, returns an array containing all matches.
+
+-   `query` can be either a CSS selector or a function.
+-   `elems` can be either an array of elements, or a single element. If it is an
+    element, its children will be queried.
+-   `options` is described below.
+
+Aliases: `default` export, `CSSselect.iterate(query, elems)`.
+
+#### `CSSselect.compile(query, options)`
+
+Compiles the query, returns a function.
+
+#### `CSSselect.is(elem, query, options)`
+
+Tests whether or not an element is matched by `query`. `query` can be either a
+CSS selector or a function.
+
+#### `CSSselect.selectOne(query, elems, options)`
+
+Arguments are the same as for `CSSselect.selectAll(query, elems)`. Only returns
+the first match, or `null` if there was no match.
+
+### Options
+
+All options are optional.
+
+-   `xmlMode`: When enabled, tag names will be case-sensitive. Default: `false`.
+-   `rootFunc`: The last function in the stack, will be called with the last
+    element that's looked at.
+-   `adapter`: The adapter to use when interacting with the backing DOM
+    structure. By default it uses the `domutils` module.
+-   `context`: The context of the current query. Used to limit the scope of
+    searches. Can be matched directly using the `:scope` pseudo-selector.
+-   `cacheResults`: Allow css-select to cache results for some selectors,
+    sometimes greatly improving querying performance. Disable this if your
+    document can change in between queries with the same compiled selector.
+    Default: `true`.
+
+#### Custom Adapters
+
+A custom adapter must match the interface described
+[here](https://github.com/fb55/css-select/blob/1aa44bdd64aaf2ebdfd7f338e2e76bed36521957/src/types.ts#L6-L96).
+
+You may want to have a look at [`domutils`](https://github.com/fb55/domutils) to
+see the default implementation, or at
+[`css-select-browser-adapter`](https://github.com/nrkn/css-select-browser-adapter/blob/master/index.js)
+for an implementation backed by the DOM.
+
+## Supported selectors
+

+    (`~`)
+-   [Attribute](https://developer.mozilla.org/en-US/docs/Web/CSS/Attribute_selectors)
+    (`[attr=foo]`), with supported comparisons:

+    -   `*=`
+    -   `^=`
+    -   `$=`
+    -   `!=`
+    -   `i` and `s` can be added after the comparison to make the comparison
+        case-insensitive or case-sensitive (eg. `[attr=foo i]`). If neither is
+        supplied, css-select will follow the HTML spec's
