+Creates a timer section on the bottom right of the screen.
+
+The timer allows to show several game related times and dates. Let's play creators can show their viewers when the recording was made, how long the recording was, the current time while recording, and the ingame time.
+
+The timer output is configurable in the advanced configuration of Minetest and provides the user with a set of variables to use and allows the date/time to be formatted as the user wants.
+
+The creator of this mod is German so the default values are set up in a way to support the German language. Since it can be configured as wanted this can be changed.
