+### Keymaps
+
+In order to support both split and non-split keyboards with the same layout, you need to use the keyboard agnostic `LAYOUT_<layout name>` macro in your keymap. For instance, in order for a Let's Split and Planck to share the same layout file, you need to use `LAYOUT_ortho_4x12` instead of `LAYOUT_planck_grid` or just `{}` for a C array.
