-
-\* See full list: https://en.wikipedia.org/wiki/ISO_3166-1#Officially_assigned_code_elements

-* `keymap.c`
-* `readme.md` *recommended*
-* `config.h` *optional*, found automatically when compiling
-* `Makefile` *optional*, found automatically when compling
-
-When adding your keymap to this list, keep it organised alphabetically (select list, edit->sort lines), and use this format:
-
-     * **folder_name** description
-
-# List of Planck keymaps
