+# Sha Default Keymap
+
+The default keymap uses a QWERTY base layout, with a secondary Colemak base layout. Both layouts have symbol placement adjustments on the outer columns, and editing keys and layers on the thumb keys.
+
+There are two extended layers:
+
+* SYMBOL: For typing additional symbols. Activated by layer-tap on the main left thumb key.
+* FUNCTION: For function and navigation keys. Activated by layer-tap on the main right thumb key.
+
+When using a Waveshare RP2040-Matrix, the [RGB Light - Lighting Layers](https://docs.qmk.fm/#/feature_rgblight?id=lighting-layers) feature is used to demonstrate how the 5x5 RGB LEDs can indicate keyboard state. The indicators are:
+
+* Base layer on the outer LED ring: QWERTY = yellow, Colemak = cyan
+* Lock status indicators using the center 3x3 LEDs: Scroll lock = blue, Caps lock = green, Num lock = red

+# Sha
+
+![Sha](https://i.imgur.com/4yuQwRXh.jpg)
+
+Sha is a 50 key ortholinear keyboard, powered by a Waveshare RP2040-Zero or Waveshare RP2040-Matrix.
+
+* Keyboard Maintainer: [Steven Karrmann](https://github.com/skarrmann)
+* Hardware Supported: Sha PCBs with either RP2040-Zero or RP2040-Matrix
+* Hardware Availability: [Sha GitHub repository](https://github.com/skarrmann/sha)
+
+Make example for this keyboard (after setting up your build environment):
+
+    make sha:default
+
+Flashing example for this keyboard:
+
+    make sha: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 (the top left key) and plug in the keyboard.
+* **Physical reset button**: Doublet-tap the EN/RESET button on the MCU board.
+* **Keycode in layout**: Press the key mapped to `QK_BOOT` if it is available.
