CUSTOM CONFIGURATION 
How do I configure my keyboard?  
Note: You will currently need a second keyboard to complete the 3rd step of this 
process. 
1. Create your configuration. 
2. Compile the firmware with your configuration. 
Use our web-based configurator tool to handle both steps at once: 
https://www.massdrop.com/mechanical-keyboards/configurator . See below for more 
information about our configurator. 
If you are comfortable with programming and want to use QMK functionality that our 
configurator does not support, you can manually create and compile your configuration 
by checking out the official QMK repository: https://github.com/qmk/qmk_firmware . 
CTRL Keyboard is in the folder "massdrop/ctrl". QMK setup instructions are here: 
https://docs.qmk.fm/#/newbs 
3. Load the firmware onto your keyboard. 
To load the firmware onto your CTRL keyboard, download the appropriate loader 
application for your computer's OS here: 
https://github.com/Massdrop/mdloader/releases/tag/1.0.3. Then follow the instructions 
here: https://github.com/Massdrop/mdloader . 
We are working with Jack and the other QMK contributors to get the loader application 
integrated into the next version of QMK Toolbox to simplify this loading process.
