 ```
 
 ### Rails
+
 Bitbot can run fine without Rails, but if you're using Rails, you can run the install generator. The generator will
 provide an initializer and mount the rack app within your routes -- be sure to update both the initializer and route if
 you change where it's mounted.

 ## Configuration

 Bitbot requires being configured, but to simplify the README it's not included here, please check the
 [config.ru](https://github.com/modeset/bitbot/blob/master/config.ru) for an example and configuration documentation.

 ## Setting up Slack

 To get all of the configuration tokens and urls, you'll need to go to Slack and add the Incoming Webhooks, and Outgoing
 Webhooks integrations. You can get your incoming url, and outgoing token by doing this, which you can then set as
 environment variables and load them into your configuration.

 ## Adding Responders
+
 There's a basic DSL for creating responders, which allows you to register help for the various commands, and define
 responder routes. Bitbot considers commands to be "routable", and so you can define them using `route`. Here's an
 example responder that specifies `category`, `help` and a single `route`. The `category` indicates grouping within the

 ### Confirmations

 Confirmations are included as a base feature, but need redis to work. Provide your own redis connection in the
 configuration and you can add confirmations (and more) to your responders. By default the configuration assumes redis is
 running locally, and is available at Redis.current -- otherwise it will try to connect to redis at the standard port.

 ## Announcing

 You can announce any message into any channel on Slack using the bot, for instance in a background job to have something
