+# RS40: Code Friendly 40% Keymap
+
+This keymap is an evolution of my previous keymap optimized for coding with a 60% keyboards like the Iris. I tried to keep the simplicity of my previous keymap with all the keys necessary for coding on a single layer in addition to the base one.
+
+Because I sometime have to use my internal keyboard I my macbook, a karabiner configuration is also provided to get most of the features of this keyboard, including the code layer / backspace on right command key etc.
+
+See [rs readme](../../../../users/rs/readme.md) for a list of other keyboards supported by this keymap.
