+# rskeys100
+
+The rskeys100 is a full size, 100% ISO keyboard with per-key RGB. 
+
+* Keyboard Maintainer: [Ryan Skidmore](https://github.com/ryanskidmore)
+* Hardware Supported: The rskeys100 matrix PCB is the only supported PCB for the switch matrix. This PCB works with any
+Pro Micro or Pro Micro alternative as the daughterboard.
+* Hardware Availability: Coming soon
+
+Make example for this keyboard (after setting up your build environment):
+
+    make ryanskidmore/rskeys100:default
+
+Flashing example for this keyboard:
+
+    make ryanskidmore/rskeys100: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
+
+To enter the bootloader, press the `RESET` button on your daughterboard PCB while it's plugged in.
