-Minetest Game mod: XPFW
+Minetest Game mod: timer
 ==========================
 See license.txt for license information.
 
-XPFW provide an API for storing values relevant for experience mechanism into player metadata. It also stores several statistic values during playtime:
-- Walked distances calculated out of velocity (important: teleporting does not influence this value)
-- accumulated distance out of comparing with last known position (important: teleporting is included in this value)
-- whole playtime on the server
-- amount of dug nodes
-- amount of build nodes
-- amount of crafted items
-- amount of occured deahts
-- amount of text messages
-- amount of logins
+This mod provides a simple countdown timer for each player. It uses xpfw for storing value, so it is also visible in the xpfw hud.
 
-For several amounts also a kind of speed is calculated, like walking speed or crafting speed.
+chat command:
+
+/cd <value> 	set countdown with <value> seconds. if not given, start with default value
+/cd r/rest		give remainign countdown time
