+## Customizing the Bot
+If you are looking to change what the bot responds to and how they respond, take a look at the `plugins/starter.py` file.  You'll see a function that gets called on all "message" type events, which has various regular expression matches that determine when the bot responds and how it responds.  Each "Plugin" is registered with the RtmBot on startup by scanning the "plugins/" directory and communicates back to the RtmBot through variables like output[] and attachments[].
