+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.

+# Sofle Keyboard
+
+![SofleKeyboard version 1](https://raw.githubusercontent.com/josefadamcik/SofleKeyboard/master/Images/IMG_20200126_114622.jpg)
+
+Sofle is 6×4+5 keys column-staggered split keyboard. Based on Lily58, Corne and Helix keyboards.
+
+More details about the keyboard on my blog: [Let me introduce you SofleKeyboard - a split keyboard based on Lily58 and Crkbd](https://josef-adamcik.cz/electronics/let-me-introduce-you-sofle-keyboard-split-keyboard-based-on-lily58.html)
+
+The current (temporary) build guide and a build log is available here: [SofleKeyboard build log/guide](https://josef-adamcik.cz/electronics/soflekeyboard-build-log-and-build-guide.html)
+
+* Keyboard Maintainer: [Josef Adamcik](https://josef-adamcik.cz) [Twitter:@josefadamcik](https://twitter.com/josefadamcik)  
+* Hardware Supported: SofleKeyboard PCB, ProMicro  
+* Hardware Availability: [PCB & Case Data](https://github.com/josefadamcik/SofleKeyboard)
+
+Make example for this keyboard (after setting up your build environment):
+
+    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.
+
+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).
