+= AsciiDoc Syntax
+:icons: font
+:stem:
+:toc: left
+:url-docs: https://asciidoctor.org/docs
+:url-gem: https://rubygems.org/gems/asciidoctor
+
+A brief reference of the most commonly used AsciiDoc syntax.
+You can find the full documentation for the AsciiDoc syntax at {url-docs}.
+
+== Paragraphs
+
+A normal paragraph.
+Line breaks are not preserved.
+// line comments, which are lines that start with //, are skipped
+
+A blank line separates paragraphs.
+
+[%hardbreaks]
+This paragraph carries the `hardbreaks` option.
+Notice how line breaks are now preserved.
+
+ An indented (literal) paragraph disables text formatting,
+ preserves spaces and line breaks, and is displayed in a
+ monospaced font.
+
+[sidebar#id.role]
+A style, ID, and/or role gives a paragraph (or block) special meaning, like this sidebar.
+
+NOTE: An admonition paragraph, like this note, grabs the reader's attention.
+
+TIP: Convert this document using the `asciidoctor` command to see the output produced from it.
+
+== Text Formatting
+:hardbreaks:
+
+.Constrained (applied at word boundaries)
+*strong importance* (aka bold)
+_stress emphasis_ (aka italic)
+`monospaced` (aka typewriter text)
+"`double`" and '`single`' typographic quotes
++passthrough text+ (substitutions disabled)
+`+literal text+` (monospaced with substitutions disabled)
+
+.Unconstrained (applied anywhere)
+**C**reate+**R**ead+**U**pdate+**D**elete
+fan__freakin__tastic
+``mono``culture
+
+.Replacements
+A long time ago in a galaxy far, far away...
+(C) 1976 Arty Artisan
+I believe I shall--no, actually I won't.
+
+.Macros
+// where c=specialchars, q=quotes, a=attributes, r=replacements, m=macros, p=post_replacements, etc.
+The European icon:flag[role=blue] is blue & contains pass:[************] arranged in a icon:circle-o[role=yellow].
+The pass:c[->] operator is often referred to as the stabby lambda.
+Since `pass:[++]` has strong priority in AsciiDoc, you can rewrite pass:c,a,r[C++ => C{pp}].
+// activate stem support by adding `:stem:` to the document header
+stem:[sqrt(4) = 2]
+
+:!hardbreaks:
+== Attributes
+
+ // define attributes in the document header; must be flush with left margin
+ :name: value
+
+You can download and install Asciidoctor {asciidoctor-version} from {url-gem}.
+C{pp} is not required, only Ruby.
+Use a leading backslash to output a word enclosed in curly braces, like \{name}.
+
+== Links
+
+[%hardbreaks]
+https://example.org/page[A webpage]
+link:../path/to/file.txt[A local file]
+xref:document.adoc[A sibling document]
+mailto:hello@example.org[Email to say hello!]
+
+== Anchors
+
+[[idname,reference text]]
+// or written using normal block attributes as `[#idname,reftext=reference text]`
+A paragraph (or any block) with an anchor (aka ID) and reftext.
+
+See <<idname>> or <<idname,optional text of internal link>>.
+
+xref:document.adoc#idname[Jumps to anchor in another document].
+
+This paragraph has a footnote.footnote:[This is the text of the footnote.]
+
+== Lists
+
+=== Unordered
+
+* level 1
+** level 2
+*** level 3
+**** level 4
+***** etc.
+* back at level 1
++
+Attach a block or paragraph to a list item using a list continuation (which you can enclose in an open block).

+# Asciidoctor core
+
+This package provides Asciidoctor core functionality:
+
+- parser
+- built-in converters
+- extensions
+
+## Install
+
+    $ npm i @asciidoctor/core --save
+
+## Usage
+
+Here is a simple example that converts AsciiDoc to HTML5:
+
+**sample.js**
+
+```javascript
+const asciidoctor = require('@asciidoctor/core')() // <1>
+const content = 'http://asciidoctor.org[*Asciidoctor*] ' +
+  'running on https://opalrb.com[_Opal_] ' +
+  'brings AsciiDoc to Node.js!'
+const html = asciidoctor.convert(content) // <2>
+console.log(html) // <3>
+```
+- <1> Instantiate the Asciidoctor.js library
+- <2> Convert AsciiDoc content to HTML5 using Asciidoctor.js
+- <3> Print the HTML5 output to the console
+
+Save the file as _sample.js_ and run it using the `node` command:
+
+    $ node sample.js
+
+You should see the following output in your terminal:
+
+```html
+<div class="paragraph">
+<p><a href="http://asciidoctor.org"><strong>Asciidoctor</strong></a> running on <a href="http://opalrb.com"><em>Opal</em></a> brings AsciiDoc to Node.js!</p>
+</div>
+```
+
+If you want to know more about Asciidoctor.js, please read the [User Manual](https://asciidoctor-docs.netlify.com/asciidoctor.js/).
