 anymatch
 ======
+Javascript module to match a string against a regular expression, glob, string,
+or function that takes the string as an argument and returns a truthy or falsy
+value. The matcher can also be an array of any or all of these. Useful for
+allowing a very flexible user-defined config to define things like file paths.
 
-wip
+Usage
+-----
+`npm install anymatch --save`
+
+```js
+var anymatch = require('anymatch');
+
+var matchers = [
+	'path/to/file.js',
+	'path/anyjs/**/*.js',
+	/foo.js$/,
+	function (string) {
+		return string.indexOf('bar') !== -1 && string.length > 10
+	}
+];
+
+anymatch(matchers, 'path/to/file.js'); // true
+anymatch(matchers, 'path/anyjs/baz.js'); // true
+anymatch(matchers, 'path/to/foo.js'); // true
+anymatch(matchers, 'path/to/bar.js'); // true
+anymatch(matchers, 'bar.js'); // false
+```
+
+You can also use the `checker` method to get a function that has already been
+bound to your matchers.
+
+```js
+var checker = anymatch.checker(matchers);
+
+checker('path/to/file.js'); // true
+```
