+You will need to adapt the below instructions so they cover _your_ board's specicific configuration. You can find screenshots of settings for common toolheads in the [Hardware Config](./hardware_config/hardware_config.md) section.
 
 If your board doesn't exist in the hardware_config folder already, then you want the Processor, Clock Reference, and Application Start offset to be set as per whatever board you are running. Set the "Build Katapult deployment application" (this is really only for updating but doesn't hurt having it enabled at this stage), and make sure "Communication Interface" is set to USB. Also make sure the "Support bootloader entry on rapid double click of reset button" is marked. It makes it so a double press of the reset button will force the board into Katapult mode. Makes re-flashing after a mistake a lot easier. Lastly, setting the Status LED GPIO Pin won't affect how katapult functions, but it will give a nice visual indicator (of an LED flashing on and off once a second) on the toolhead to show the board is sitting in Katapult mode.
