+# GMMK PRO (ISO)
+
+A tenkeyless 75% keyboard made and sold by Glorious LLC. Equipped with the STM32 ARM Cortex-M4 microcontroller, with support for rotary encoders and three additional layouts. [More info at Glorious](https://www.pcgamingrace.com/products/glorious-gmmk-pro-75-barebone-black-reservation)
+
+* Keyboard Maintainer: [GloriousThrall](https://github.com/GloriousThrall)
+* Hardware Supported: GMMK Pro
+* Hardware Availability: [GloriousPCGaming.com](https://www.pcgamingrace.com/products/glorious-gmmk-pro-75-barebone-black-reservation)
+
+Make example for this keyboard (after setting up your build environment):
+
+    make gmmk/pro/iso:default
+
+Flashing example for this keyboard:
+
+    make gmmk/pro/iso:default:flash
+
+To reset the board into bootloader mode, do one of the following:
+
+* Hold the Reset switch mounted on the bottom side of the PCB while connecting the USB cable
+* Hold the Escape key while connecting the USB cable (also erases persistent settings)
+* Fn+Backspace will reset the board to bootloader mode if you have flashed the default QMK keymap
+
+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).
