 ===========
 This mod adds basic support for mana to Minetest.
 It provides a simple API to set, get, add and subtract the mana (and maximum) mana of any player.
+The mod also automatically allows for regenerating Mana automatically.
+By default, each player spawns with 0/200 mana, and regenerates 1 mana per tenth of a second. All
+these values can be configured with the server settings (`minetest.conf`) and it is highly advised to do
+so if you plan to integrate this mod into a subgame.
+
 The API documentation is in the file API.md.
 
 If the mod “HUD bars” [hudbars] is installed, a blue bar will be added to the HUD showing the player's mana reserves.

 This mod can be configured with minetest.conf! The following settings are accepted:
 
-* `mana_default_max`: Initial max. mana given to new players.
+* `mana_default_max`: Initial max. mana given to new players. Default: `200`. This value must be non-negative.
+* `mana_default_regen`: Initial regenerated mana per “mana tick”. Default: `1`. This value must be non-negative.
+* `mana_regen_timer`: The length of a “mana tick” in seconds. Each player will get his/her mana increased by the current
+  regen value per mana tick. Default: `0.1`. This value must be positive, also try to avoid very small values
+  as those could probably stress your machine a lot.
