+
+![ph100](https://cdn.shopify.com/s/files/1/0470/8814/0443/products/DSCF0064_1080x.png)
+
+The ph100 is a 100-key modular keyboard from Phrygian Design.
+
+* Keyboard Maintainer: https://github.com/phrygiandesign
+* Hardware Supported: ph100 PCB
+* Hardware Availability: https://phrygiandesign.com/products/ph100-mechanical-keyboard
+* Keyboard support: contact@phrygiandesign.com
+
+Make example for this keyboard:
+
+ make phrygian/ph100:default
+
+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).
+
+#### Note: Booting into the STM32 USB Bootloader
+The STM32F042 range of microcontrollers have problems with entering into the USB bootloader with QMK's bootloader key sequence.
+To boot into the bootloader, apply power to the keyboard while holding down "SW0" on the bottom of PCB near the USB port.
