+# Feature keymap
+
+This keymap is heavily inspired by the [miryoku](https://github.com/manna-harbour/miryoku) layout.
+
+It defaults to a [COLEMAK mod dh](https://colemakmods.github.io/mod-dh/) layer, but a QWERTY and a gaming layer are available from the `sys` layer.
+
+It uses the following features:
+
+-   Home row modifiers
+-   Usual special layers (`media`, `navigation`, `mouse`, `symbols`, `numbers`, `functions`, `system`)
+-   Combos (to access the `sys` layer by pressing both external thumb keys)

+# Test keymap
+
+Inspired by the [ferris sweep test keymap](https://github.com/qmk/qmk_firmware/tree/master/keyboards/ferris/keymaps/test).
+A simple QWERTY keymap used to test the keyboard. As such, it should not be used for other purposes than testing.
