+# Pierce
+
+
+
+A modular wireless / semi-wireless split 36 key keyboard. Wireless version uses a dongle as a receiver for both halves while the semi-wireless version uses the wired half as a receiver for the wireless half.
+Supports MX, Choc V1 and Alps switches.
+
+ * Keyboard Maintainer: [durken1](https://github.com/durken1/)
+ * Hardware Supported: pierce 2.0
+ * Hardware Information: [pierce](https://github.com/durken1/pierce)
+
+Make example for this keyboard (after setting up your build environment):
+
+ make pierce:default
+
+Flashing example for this keyboard:
+
+ make pierce: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 2 ways:
+
+* **Physical reset button**: Briefly press the button on the dongle / wired half
+* **Keycode in layout**: Press the key mapped to `RESET` if it is available
