+# idobao id80
+
+This is my layout for the idobao id80. It depends of my [user files](../../../../users/rverst)
+and the main goal is to give an convenient and unified access to some special keys
+(umlauts, ß, €) for different operating systems (Mac, Windows and Linux).
+
+## Overview
+
+- Layer 0 is the base US-ANSI layout with Mac-style system keys and a OSL-Key for Layer 1 right of the space bar.
+- Layer 1 has the special keys and some media-functions like mute, volume up/down etc.
+- Layer 2 and 3 are basically the same as Layer 0 and 1 but in Colemak-Layout
+- Layer 4 and 5 has some functions like switching the keyboard mode, switching the default layer etc.
+
+
+## Keyboard modes
+
+- *F1:* Mac Unicode mode (use 'Unicode Hex Input' as input source)
+- *F2:* Windows Unicode mode (use [WinCompse](https://github.com/SamHocevar/wincompose) software)
+- *F3:* Linux Unicode mode (not tested yet but should work out of the box)
+-  *1:* Mac legacy mode (uses option-sequences, e.g. `<option>+u a` for an `ä`), if I'm not able to set the input source
+-  *2:* Windows legacy mode (uses altgr-sequences e.g. `<altgr>+0228` for an `ä`, if I'm not able to use WinCompose)
+
+Layer 4 to switch the modes temporary, layer 5 to switch and save to eeprom.

+# Overview
+
+This is my user space, main goal is to unify the experience between different 
+keyboard models and operating systems.
+My native language is German and I almost exclusively use keyboards in the
+US-ANSI layout. I find this layout the most practical for programming as
+far as the placement of special characters is concerned. However, when I write
+in German, I miss a few special characters like umlauts, etc.
+Since I also use different operating systems (MacOS, Linux and Windows)
+and especially Windows and MacOS behave very differently regarding the input
+of such characters (under Linux there is at least the Compose key).
+So I needed a hardware solution, and that's how I came to QMK.
+
+Here are defined some key codes to put the keyboard in different modes
+(Mac, Windows, Linux) and the corresponding functions to make the input.
+And some logic to store the respective mode and load it at boot time.
+
+You'll find a proper layout here: [keyborads/id80/keymaps/rverst](../../keyboards/id80/keymaps/rverst)
