+# Acheron Aχξρων 40-SM-O-MX-TH-WI (Codename "SharkPCB") QMK firmware
+
+
+
+
+
+This is the QMK firmware repository for the Shark, updated until [revision Alpha](https://github.com/Gondolindrim/SharkPCB/releases/tag/Alpha).
+
+The SharkPCB is an Open-Hardware guidelines compliant PCB which files can be found at [this link](https://github.com/Gondolindrim/SharkPCB). Its designer and maintainer is [Gondolindrim](https://github.com/Gondolindrim).
+
+See the [AcheronDocs](https://gondolindrim.github.io/AcheronDocs/shark/intro.html) page for the SharkPCB full documentation.
+
+Make example for this keyboard (after setting up your build environment):
+
+ make acheron/shark: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).
