+# Hydrogen Deskpad
+
+A 5 key macropad with an encoder, that can be mounted to a desk or below your monitor.
+
+* Keyboard Maintainer: [Hydrogen BD](https://www.facebook.com/hgenbd/)
+* Hardware Supported: [5k Deskpad](https://fb.watch/akRLW7s-UT/)
+
+Make example for this keyboard (after setting up your build environment):
+
+ make h0oni/deskpad:default
+
+## Bootloader
+
+Enter the bootloader in 2 ways:
+
+* **Bootmagic reset**: Hold down the key at (0,0) in the matrix (the left most key) and plug in the keyboard.
+* **Physical reset button**: Press the button at the back of the PCB twice to enter into the bootloader mode.
+
+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).<
