 ====================================
 
 This mod calculates a hash code of a player's name and chooses a texture for him according to this hash code.
-There are 8 skins as default, you can change them by replacing player_hash_skin_<integer>.png with the skin you want.
-If you want more than 8 skins, change line 10 in init.lua:
-hash = hash%8 to hash = hash%<count of skins>
-and add additional skins to the textures folder.
+Eight default skins are shipped with the mod, you can add an arbitrary number of skins on your own by adding them to the textures folder. The simple_skins mod is supported and its skins will be used instead of the skins in the textures folder when it is detected.
