+## Installation
+
+```sh

+
+## Usage
+
+```javascrpt

+
+### `resolve(filename, [require])`

+Returns `null` if the file can't be required, otherwise it returns an absolute filename string.
+
+#### Example
+
+```javascript
+if (require("try-resolve")("/home/sebastian/file")) {
+  // this file can be required
+} else {
+  // it can't
+}
+```
+
+### `resolve.relative(filename)`
+
+Resolve a filename relative to the cwd.
