-Make example for this keyboard (after setting up your build environment):
+## Building the firmware
+
+**You must specify the shield version when compiling/flashing the firmware.**
+
+The template is:
+
+```shell
+qmk compile -kb bastardkb/skeletyl/{VERSION}/elitec -km {KEYMAP}
+```
+
+| Shield Version  | default                                                         | via                                                         |

 This keyboard is made to be used with the Miryoku layout, do not use the default keymap.
