+# ♬ OmgParser
+
+**OmgParser** is a JavaScript applet which reads standard MIDI files and emits JSON events in real time.
+
+This player does not generate any audio, but by attaching a handler to the event emitter you can trigger any code you like which could play audio, control visualizations, feed into a MIDI interface, etc.
+
+## Demos
+
+To be updated... 👀
+
+## Getting Started
+
+Using MidiWriterJS is pretty simple.  Create a new player by instantiating `MidiPlayer.Player` with an event handler to be called for every MIDI event.  Then you can load and play a MIDI file.
+
+```js
+const MidiPlayer = require('midi-player-js');
+
+// Initialize player and register event handler
+const Player = new MidiPlayer.Player(function(event) {
+	console.log(event);
+});
+
+// Load a MIDI file
+Player.loadFile('./test.mid');
+Player.play();
+```
+
+## Player Events
+
+There are a handful of events on the `Player` object which you can subscribe to using the `Player.on()` method.  Some events pass data as the first argument of the callback as described below:
+
+```js
+Player.on('fileLoaded', function() {
+    // Do something when file is loaded
+});
+
+Player.on('playing', function(currentTick) {
+    // Do something while player is playing
+    // (this is repeatedly triggered within the play loop)
+});
+
+Player.on('midiEvent', function(event) {
+    // Do something when a MIDI event is fired.
+    // (this is the same as passing a function to MidiPlayer.Player() when instantiating.
+});
+
+Player.on('endOfFile', function() {
+    // Do something when end of the file has been reached.
+});
+```
+
+Note that because of a common practice called "running status" many MIDI files may use `Note on` events with `0` velocity in place of `Note off` events.
