# Userspace: sharing code between keymaps If you use more than one keyboard with a similar keymap, you might see the benefit in being able to share code between them. Create your own folder in `users/` named the same as your keymap (ideally your github username, ``) with the following structure: * `/users//` (added to the path automatically) * `readme.md` * `rules.mk` (included automatically) * `.h` (optional) * `.c` (optional) `.c` will need to be added to the SRC in `rules.mk` like this: SRC += .c Additional files may be added in the same way - it's recommended you have one named ``.c/.h though. All this only happens when you build a keymap named ``, like this: make planck: For example, make planck:jack Will include the `/users/jack/` folder in the path, along with `/users/jack/rules.mk`. ## Readme Please include authorship (your name, github username, email), and optionally [a license that's GPL compatible](https://www.gnu.org/licenses/license-list.html#GPLCompatibleLicenses). ## Example For a brief example, checkout `/users/_example/` until we have more reasonable and useful examples.
