+# SpacebarRacecar US-International Preonic Keymap for German PCs
+
+This keymap emulates most keys of the US-International layout on PCs that have German set as input language.  
+This allows the use of the keyboard on any PC in Germany without the need to change any settings.
+The keymap is mostly based on the Preonic default layout but adds essential features for german input, like access to Ä, Ö, Ü, ß.
