+# System76 Launch Configurable Keyboard (launch_1)
+
+
+
+The Launch Configurable Keyboard is engineered to be comfortable, fully customizable, and make your workflow more efficient.
+
+- High-speed USB Hub
+- Works on Linux, Windows and macOS
+- 100% Open Source
+- Made in Colorado
+
+Additional Launch Keyboard resources:
+
+- Keyboard Maintainer: [System76](https://github.com/system76)
+- Hardware Supported: [System76 Launch GitHub Repository](https://github.com/system76/launch)
+- Hardware Availability: [Shop System76](https://system76.com/accessories/launch)
+
+## Building Firmware
+
+To build the firmware using `make` (after setting up the build environment), e.g.:
+
+```bash
+make -r system76/launch_1:default
+```
+
+Equivalently, using the QMK CLI:
+
+```bash
+qmk compile -kb system76/launch_1 -km default
+```
+
+## Flashing Firmware (DFU)
+
+To build and flash the firmware on the keyboard, e.g.:
+
+```bash
+make -r system76/launch_1:default:flash
+```
+
+Equivalently, using the QMK CLI:
+
+```bash
+qmk flash -kb system76/launch_1 -km default
+```
+
+## Flashing Firmware (ISP)
+
+To flash the firmware (and/or bootloader) using ISP refer to the [_ISP Flashing Guide_](https://docs.qmk.fm/#/isp_flashing_guide).
+
+> **Factory fuse values** => Low: `0x5E`, High: `0x99`, Extended: `0xF3`, Lock Bits: `0xFF`
+
+## Environment Setup
+
+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. If new to QMK, start with the [_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 (Escape) and plug in the keyboard.
+- **Keycode in layout**: Press the key mapped to `RESET` in the second layer (Escape).
+- **Electrical reset**: Briefly short AVR ISP's GND (6) and RST (5) pads on the back of the PCB.
