-**Tiny (~200b) functional event emitter / pubsub.**
+## Why Mitt?
+
+- **Microscopic:** weighs less than 200 bytes gzipped
+- **Useful:** a wildcard `"*"` event type listens to all events
+- **Famliar:** same names & ideas as [Node's EventEmitter](https://nodejs.org/api/events.html#events_class_eventemitter)
+- **Functional:** methods don't rely on `this`
+- **Great Name:** somehow [mitt](https://npm.im/mitt) wasn't taken
 
-**It's tiny:** no dependencies and only **190 bytes** when gzipped _(250b without)_.

+## Usage
+
+After installing via `npm install --save mitt`:
+
+```js
+import mitt from 'mitt'
+
+let emitter = mitt()
+
+// listen to an event
+emitter.on('foo', e => console.log('foo', e) )
+
+// listen to all events
+emitter.on('*', (type, e) => console.log(type, e) )
+
+// fire an event
+emitter.emit('foo', { a: 'b' })
+
+// working with handler references:
+function onFoo() {}
+emitter.on('foo', onFoo)   // listen
+emitter.off('foo', onFoo)  // unlisten
 ```
