+## Usage
+
+micro match exposes a single method which allows you to match a route binding to it's real world counterpart and return it's bindings.
+
+```javascript
+const {id} = match('/users/:id', '/users/1');
+```
+Parameters are defined as a comma followed by an alias to bind it's value to.
+
+You can also create optional parameters by attaching a `?` suffix. This will allow both `/users` and `/users/1` to be matched.
+
+Now you will be able to access the `id` parameter with the value of `1` and handle it however ever you like.
