+
+HTTP verbs that Node.js core's HTTP parser supports.
+
+This module provides an export that is just like `http.METHODS` from Node.js core,
+with the following differences:
+
+  * All method names are lower-cased.
+  * Contains a fallback list of methods for Node.js versions that do not have a
+    `http.METHODS` export (0.10 and lower).
+  * Provides the fallback list when using tools like `browserify` without pulling
+    in the `http` shim module.
+
+## Install
+
+```bash
+$ npm install methods
+```
+
+## API
+
+```js
+var methods = require('methods')
+```
+
+### methods
+
+This is an array of lower-cased method names that Node.js supports. If Node.js
+provides the `http.METHODS` export, then this is the same array lower-cased,
+otherwise it is a snapshot of the verbs from Node.js 0.10.
