+A TKL PCB TypeC for Serratus keyboard.
+
+* Keyboard Maintainer: [mechlovin](https://github.com/mechlovin)
+* Hardware Supported: Serratus, Atmega32u4
+* Hardware Availability: [Geekhack GB](https://geekhack.org/index.php?topic=112768.0)
+
+Make example for this keyboard (after setting up your build environment):
+
+    make mechlovin/serratus:default
+
+Flashing example for this keyboard:
+
+    make mechlovin/serratus: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).
+
+**Reset Key:** To put the Serratus PCB into bootloader, push reset swith on the bottom of the PCB.
