 # disco
-A Pythonic Discord library built for simplicity and extendability. Supports 2.x/3.x versions of Python. Uses gevent.
+Disco is a simple and extendable library for the [Discord API](https://discordapp.com/developers/docs/intro).
 
+- Expressive, functional interface that gets out of the way
+- Built for high-performance and efficiency
+- Configurable and modular, take the bits you need
+- Full support for Python 2.x/3.x
+- Evented networking and IO using Gevent
 
-## TODOS
+## Installation
-- Permissions/Roles support
-- Plugin/Library reloading
-  - Abstract GatewayClient out into the WebsocketProcessProxy
-  - Abstract VoiceClients to run in a seperate process
-- Voice Support
 
+Disco was built to run both as a generic-use library, and a standalone bot toolkit. Installing disco is as easy as running `pip install disco`, however some extra packages are recommended for power-users, namely:
+
+|Name|Reason|
+|requests[security]|adds packages for a proper SSL implementation|
+|rapidjson|provides a Python implementation of the C rapidjson library, improves performance|
+
+## Examples
+
+Simple bot using the builtin bot authoring tools:
+
+```python
+from disco.bot import Bot, Plugin
+
+
+class SimplePlugin(Plugin):
+    # Plugins provide an easy interface for listening to Discord events
+    @Plugin.listen('ChannelCreate')
+    def on_channel_create(self, event):
+        event.channel.send_message('Woah, a new channel huh!')
+
+    # They also provide an easy-to-use command component
+    @Plugin.command('ping')
+    def on_ping_command(self, event):
+        event.msg.reply('Pong!')
+
+    # Which includes command argument parsing
+    @Plugin.command('echo', '<content:str...>')
+    def on_echo_command(self, event, content):
+        event.msg.reply(content)
+
+if __name__ == '__main__':
+    Bot.from_cli(
+        SimplePlugin
+    ).run_forever()
+```
+
+Using the default bot configuration, we can now run this script like so:
+
+`./simple.py --token="MY_DISCORD_TOKEN"`
+
+And commands can be triggered by mentioning the bot (configued by the BotConfig.command\_require\_mention flag):
