+## Building a Keymap
+
+You should be able to build the keyboard keymap with a command in this format:
+
+ make <keyboard>:<layout>
+
+### Conflicting layouts
+When a keyboard supports multiple layout options,
+
+ LAYOUTS = ortho_4x4 ortho_4x12
+
+And a layout exists for both options,
+```
+layouts/
++ community/
+| + ortho_4x4/
+| | + <layout>/
+| | | + ...
+| + ortho_4x12/
+| | + <layout>/
+| | | + ...
+| + ...
+```
+
+The FORCE_LAYOUT argument can be used to specify which layout to build
+
+ make <keyboard>:<layout> FORCE_LAYOUT=ortho_4x4
+ make <keyboard>:<layout> FORCE_LAYOUT=ortho_4x12
+
