+# Keybow 2040
+
+![Keybow 2040 board](https://i.imgur.com/WDGDOkb.jpeg)
+
+The [Pimoroni Keybow 2040](https://shop.pimoroni.com/products/keybow-2040) is a 16 key mechanical macropad
+controlled by a Raspberry Pi RP2040, with Kailh hot swap sockets and
+per key RGB lighting, in a decorative FR4 sandwich. The Keybow 2040 is
+also known by its codename Venus Dust, or its product codes of the
+form PIM56x.
+
+* Original Keyboard Maintainer: [Tony Finch](https://github.com/fanf2)
+* Keyboard Maintainer: [Wilfried Jeanniard](https://github.com/willoucom) and [Sandy Macdonald](https://github.com/sandyjmacdonald)
+* Hardware Supported: Keybow 2040
+* Hardware Availability: [Pimoroni](https://shop.pimoroni.com/products/keybow-2040)
+
+## Usage
+
+The bootloader button is used to switch from one layer to another, the first layer is used for macros and shortcuts, while the second layer controls RGB lights. You can modify this behavior using the QMK configurator.
+
+## Build
+
+Make example for this keyboard (after setting up your build environment):
+
+    make pimoroni/keybow2040:default
+
+Flashing example for this keyboard:
+
+    make pimoroni/keybow2040: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 top left key and plug in the keyboard
+* **Physical reset button**: Hold down BOOTSEL while pressing RESET
+* **Keycode in layout**: Press the key mapped to `QK_BOOT` if it is available
