+AMJ40 Default Layout
+=====================
+
+##Quantum MK Firmware
+For the full Quantum feature list, see the parent readme.md.
+
+# Features
+* Based on a combination of the original AMJ40 keymap from the TMK firmware as well as the Planck Ortholinear keyboard's "Lower," "Raise," and "Adjust" layers.
+* View the keymap.c file to understand they layout of the keymap.
+* Has keys to toggle both the switch LEDs and underglow LEDs.

+AMJ40 keyboard firmware
+======================
+DIY/Assembled compact 40% keyboard.
+
+Ported by N.Hou from the original TMK firmware.
+
+*Supports both backlight LEDs as well as RGB underglow. 
+
+*For reference, the AMJ40 uses pin D3 for underglow lighting.
+
+## Quantum MK Firmware
+
+For the full Quantum feature list, see [the parent readme.md](/readme.md).
+
+## Building
+
+Download or clone the whole firmware and navigate to the keyboards/amj40
+folder. Once your dev env is setup, you'll be able to type `make` to generate
+your .hex - you can then use `make dfu` to program your PCB once you hit the
+reset button. 
+
+Depending on which keymap you would like to use, you will have to compile
+slightly differently.
+
+### Default
+To build with the default keymap, simply run `sudo make all`.
+The .hex file will appear in the root of the qmk firmware folder.
+
+
+
+
+### Original tmk firmware
+The original firmware that was used to port to qmk can be found [here](https://github.com/AMJKeyboard/AMJ40).
