+# Pteron
+
+![Pteron](https://i.imgur.com/9QhPlVD.jpg)
+
+An ergonomic keyboard heavily inspired by the [Atreus](https://github.com/technomancy/atreus), [Iris](https://github.com/keebio/iris-case) and [Atreis](https://github.com/dekonnection/atreis) keyboards. More info and files for laser cutting plates and case are in the [Pteron repository](https://github.com/FSund/pteron-keyboard).
+
+Keyboard Maintainer: [Filip Sund](https://github.com/FSund)  
+Hardware Supported: Pro Micro  
+Hardware Availability: Handwired, no PCB's available (for now)
+
+Make example for this keyboard (after setting up your build environment):
+
+    make handwired/pteron: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).
