+Compressible `Content-Type` / `mime` checking.
+
+## Installation
+
+```sh
+$ npm install compressible
+```
+
+## API
+
+<!-- eslint-disable no-unused-vars -->
+
+```js
+var compressible = require('compressible')
+```
+
+### compressible(type)
+
+Checks if the given `Content-Type` is compressible. The `type` argument is expected
+to be a value MIME type or `Content-Type` string, though no validation is performed.
+
+The MIME is looked up in the [`mime-db`](https://www.npmjs.com/package/mime-db) and
+if there is compressible information in the database entry, that is returned. Otherwise,
+this module will fallback to `true` for the following types:
+
+  * `text/*`
+  * `*/*+json`
+  * `*/*+text`
+  * `*/*+xml`
+
+If this module is not sure if a type is specifically compressible or specifically
+uncompressible, `undefined` is returned.
+
+<!-- eslint-disable no-undef -->
+
+```js
+compressible('text/html') // => true
+compressible('image/png') // => false
+```
