+
+![Imgur Image](https://imgur.com/t7Zi2w3h.jpg) 
+![Imgur Image](https://i.imgur.com/5xlKJlBh.jpg)
+
+
+A macropad 5x4 for MerryPCB.
+
+* Keyboard Maintainer: [Alhen](https://github.com/alhenx)
+* Hardware Supported: MerryPCB
+
+Make example for this keyboard (after setting up your build environment):
+
+Macropad:
+
+    make alhenkb/macropad5x4:default
+    
+Numpad:
+
+    make alhenkb/macropad5x4:numpad
+
+Flashing example for this keyboard:
+
+Macropad:
+
+    make alhenkb/macropad5x4:default:flash
+    
+
+Numpad:
+
+    make alhenkb/macropad5x4:numpad:flash
+
+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).
+
+## Bootloader
+
+Enter the bootloader in 3 ways:
+
+* **Bootmagic reset**: Hold down the key at (0,0) in the matrix (usually the top left key or Escape) and plug in the keyboard
+* **Physical reset button**: Briefly press the button on the back of the PCB - some may have pads you must short instead
+* **Keycode in layout**: Press the key mapped to `QK_BOOT` if it is available
