+Layout in [Keyboard Layout Editor](http://www.keyboard-layout-editor.com/#/gists/76efb423a46cbbea75465cb468eef7ff) and [adjust layer](http://www.keyboard-layout-editor.com/#/gists/4bcf66f922cfd54da20ba04905d56bd4)
+
+
+Features:
+
+- Symmetric modifiers (CMD/Super, Alt/Opt, Ctrl, Shift)
+- Various modes, can be switched (using Adjust layer and the selected one is stored in EEPROM.
+- Modes for Qwerty and Colemak support
+- Modes for Mac vs Linux/Win support -> different order of modifiers and different action shortcuts on the "UPPER" layer (the red one in the image). Designed to simplify transtions when switching between operating systems often.
+- The OLED on master half shows selected mode and caps lock state and is rotated.
+- Left encoder controls volume up/down/mute. Right encoder PGUP/PGDOWN.

+    make sofle:default
+
+Flash the default keymap: 
+
+    make sofle:default:avrdude
+
+Press reset button on he keyboard when asked.
+
+Disconnect the first half, connect the second one and repeat the process.
