+Classes - Player Classes
+========================
+
+Playable character classes, currently including human, dwarf and elf.
+Does nothing much besides altering the visual appearance of the character model.
+Different classes have no special abilities as yet.
+
+To change class issue the chat command: /class human | dwarf | elf
+
+To view your current class simply type /class
+
+Changing class requires the 'class' privilege.
+
+Default class can be set via minetest.conf, eg: classes_default_class = dwarf
