+
+Make example for this keyboard (after setting up your build environment):
+
+    make omkbd/ergodash/rev1:default
+
+See [build environment setup](https://docs.qmk.fm/#/getting_started_build_tools) then the [make instructions](https://docs.qmk.fm/#/getting_started_make_guide) for more information.
+
+Install Example: (for pro micro)

+
+Note:  
+  "rev1" is for PCB ver 1.0,1.1,1.2  
+  **The original Rev 1 was owned only by the designer. Therefore, Rev1 has been removed. Since the current PCB is Rev1, we changed Rev2 to Rev1 to match the firmware version.**
