Slack-Chat is a very simple Slack-RTM implementation. It very simply allows the capturing and responding of messages and comes bundled with a simple command example.
Try running docs master routing, for instance. The code for this command resides in src/commands/docs.js and is enabled in src/commands/_impl.js. You can see my sample message handling function that passes a message to the handler in the bin/app.js file, towards the bottom.
To run this all you need to do is have node installed and setup the config file in src/config.js. You'll need your User ID for the bot (so it doesn't respond to it's self!) and a Slack API key from your team (refer to Slack's own documentation for retrieving this).
Once done, execution is simple:
./bin/start
