+## Features
+
+- Raspberry Pi RP2040 Chip + 8MB Flash memory - Dual-core Cortex M0+ at ~130MHz with 264KB of RAM.
+- 3x4 Mechanical key switch sockets - accepts any Cherry MX-compatible switches. Individually tied to GPIO pins (not matrix wired)
+- One NeoPixel RGB LED per switch, on north side.
+- Rotary encoder, 20 detents per rotation, with push-switch on GPIO pin. Push switch is also used for entering bootloader mode when held down on power-up or reset.
+- 128x64 SH1106 Monochrome OLED display - On high-speed hardware SPI port for quick updates.
+- 8mm Speaker/Buzzer - With Class D amplifier and RC filter, can be used to make simple beeps and sounds effects. (Unsupported for now)
+- STEMMA QT Connector - Allows adding any I2C sensors/displays/devices with plug-and-play cables.
+- Reset button - On the side, for quick restarting, press it twice to enter bootloader.
+- Four M3 mounting bosses - Make custom enclosures easily.
+
+## Bootloader
+
+Enter the bootloader in 3 ways:
+
+* **Bootmagic reset**: Hold down the rotary encoder push-button on power-up or reset.
+* **Physical reset button**: Press twice the button on the side while the board is connected.
+* **Keycode in layout**: Press the key mapped to `QK_BOOT` if it is available.
