 # Building QMK with GitHub Userspace
 
 This is an intermediate QMK tutorial to setup an out-of-tree build environment with a personal GitHub repository.

Keymap files will instead be stored in your own personal GitHub repository, in [Userspace](https://docs.qmk.fm/#/feature_userspace) format, and built with an action workflow.
