 ## Configuration
 
 To customize, add config options to your `config/[YOUR KEYBOARD SHIELD].conf` like so:
+
 ```ini
 CONFIG_PROSPECTOR_USE_AMBIENT_LIGHT_SENSOR=n
 CONFIG_PROSPECTOR_FIXED_BRIGHTESS=80
 ```
 
 ### Available config options:
-| Name                                              | Description                                                               | Default      |
