+![Rama Works x Machine Industries M4-A](https://images.squarespace-cdn.com/content/v1/563c788ae4b099120ae219e2/1479361502907-WL2VUR210J6RFD84WH2E/image-asset.jpeg?format=1500w)
+
+A tiny 4-key macropad designed by Rama Works.
+
+* Keyboard Maintainer: [naut](https://github.com/nautxx)
+* Hardware Supported: Rama Works x Machine Industries M4-A PCB
+* Hardware Availability: [Rama Works Store](https://ramaworks.store/)
+
+Make example for this keyboard (after setting up your build environment):
+
+    make machine_industries/m4_a:default
+
+Flashing example for this keyboard:
+
+    make machine_industries/m4_a:default: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 `RESET` if it is available
