+# About this keymap
+
+This keymap is based on the qwertz layout.
+It has a key for pressing the left control and the left alt key at once.
+
+Linux makes a difference between AltGr and Control + Alt. Some keybindings are easier to press now.
+
+Also, I added a layer for pressing Control + Alt + F-Keys very fast.
+
+# Layer
+
+Each layer in the *keymap.c*-file has a comment showing the mappings of the layer.
