+
+Useful support functions and an extensive progress tracker, topical lessons
+and the ability to create your own practice lessons make learning to type
+easy.

+Grundeinstellungen (Generell Settings) → Sprache (Language) and change from
+Deutsch to English. The you have restart the program to have the change take
