+# diverge3
+
+A split 5x7 keyboard with 3 thumb keys. Made by [Unikeyboard](https://unikeyboard.io).
+
+Keyboard Maintainer: [IslandMan93](https://github.com/islandman93)
+Hardware Supported: Pro Micro
+Hardware Availability: [Diverge 3](https://unikeyboard.io/product/diverge/)
+
+Make example for this keyboard (after setting up your build environment):
+
+    make diverge3:default
+
+See [build environment setup](https://docs.qmk.fm/build_environment_setup.html) then the [make instructions](https://docs.qmk.fm/make_instructions.html) for more information.
+
+# Reflashing Animus
+Reflashing the stock firmware is pretty easy. Just follow the same steps in the [original guide](https://imgur.com/a/8UapN). You will have to manually reset the Pro Micro (by shorting the GND and RST) during the upload step. Then reapply your keymap through Arbites.
