+# MIME Types
+
+The ultimate mime type utility.
+Similar to [mime](https://github.com/broofa/node-mime) except:
+
+- No `new Mime()` business, so you could do `var lookup = require('mime-types').lookup`
+- No fallbacks, so do `var type = mime.lookup('unrecognized') || 'application/octet-stream'`
+- Additional mime types are added such as jade and stylus. Feel free to add more!
+- Browser support via Browserify and Component by converting lists to JSON files
+
+Otherwise, the API is compatible.
+
+## Adding Types
+
+If you'd like to add additional types,
+simply create a PR with a link to where it's defined.
+
+Do __NOT__ edit `mime.json` or `node.json`.
+Those are pulled using `build.js`.
+You should only touch `custom.json`.
+
+## API
+
+### mime.lookup(path)
+
+Lookup the mime type associated with a file.
+If no type is found, returns `false`.
+
+### mime.extension(type)
+
+Get the default extension for the type
+
+### mime.charsets.lookup(type)
+
+Lookup the given charset of a mime type.
+
+### mime.contentType(type)
+
+Create a full `content-type` header given a mime-type or extension.
+
+### mime.types[extension] = type
+
+Lookup a type via extension.
+
+### mime.extensions[type] = [extensions]
+
+Lookup all the associated extensions of a mime type.
+
+### mime.define(types)
+
+Globally add definitions.
+`types` must be an object of the form:
+
+```js
+{
+  "<mime-type>": [extensions...],
+  "<mime-type>": [extensions...]
+}
+```
+
+See the `.json` files in `lib/` for examples.
