+# Compound
+
+![Compound](https://imgur.com/0DC9F9dh.jpg)
+
+A compact 60% Compound keyboard with fixed Tsangan style layout.
+
+* Keyboard Maintainer: [yumagulovrn](https://github.com/yumagulovrn)  
+* Hardware Supported: Compound PCB
+* Hardware Availability: [GeekHack IC](https://geekhack.org/index.php?topic=111187.0)
+
+## Entering bootloader mode
+
+Keyboard doesn't have dedicated RESET button on the PCB, however, there are alternatives:
+
+### Bootmagic
+
+Hold down ESC while plugging the keyboard in.
+
+### Shorting RESET pin
+
+Short GND and RST pads on the bottom of the keyboard. Location of the pads can be seen [here](https://imgur.com/uw7Zz7Y.jpg).
+
+
+## Building keyboard firmware
+
+Make example for this keyboard (after setting up your build environment):
+
+    make compound:default
+
+See the [build environment setup](https://docs.qmk.fm/#/getting_started_build_tools) and the [make instructions](https://docs.qmk.fm/#/getting_started_make_guide) for more information. Brand new to QMK? Start with our [Complete Newbs Guide](https://docs.qmk.fm/#/newbs).
