+KMAC Happy keyboard firmware
+======================
+
+The KMAC Happy is a HHKB layout 60% keyboard. It is programmed with the 'KMAC KEY MAP' original.
+
+## Hardware
+Columns 7-14 and rows 0-4 are wired directly to the ATmega32U4, and columns 0-7 are wired to the [74HC237D demultiplexer](https://www.mouser.de/datasheet/2/916/74HC237-1319445.pdf). Capslock is on E2 and also triggers a reset if held when plugging the cable in.
+
+There is only one individually controllable led, which is the Capslock key.
+
+The ATmega32U4 runs on an external crystal on 8mhz, so you'll have to change the bitclock on the ISP programmer if you're unable to read or write the chip.
+
+## How to build
+
+```
+make kmac_happy:default
+or
+make kmac_happy:vial
+```
+
+## How to flash
+Hold the capslock key while plugging in the USB and flash the .hex file using QMK Toolbox or Atmel FLIP.
+
+## **IMPORTANT**
+
+The backlight feature does not work in current version, I still does not figure out a way to add backlight function without breaking the firmware size limitation.
+
+May be fixed in future release.
+
+```bash
+ * The firmware is too large! 29052/28672 (380 bytes over)
+```
+
+## Thanks
+
+Thanks to Evy Dekkers for his great contribution, which makes the porting much easily.
