 Texture Overrides
 -----------------

-texture overrides. To do this, create a file in a texture pack
-called override.txt
+You can override the textures of nodes and items from a
+texture pack using texture overrides. To do this, create one or
+more files in a texture pack called override.txt
 
 Each line in an override.txt file is a rule. It consists of
 
-	nodename face-selector texture
+	itemname target texture
 
 For example,
 
 	default:dirt_with_grass sides default_stone.png
 
-You can use ^ operators as usual:
+or
+
+	default:sword_steel inventory my_steel_sword.png
+
+You can list multiple targets on one line as a comma-separated list:
+
+	default:tree top,bottom my_special_tree.png
+
+You can use texture modifiers, as usual:
 
 	default:dirt_with_grass sides default_stone.png^[brighten
 
-Here are face selectors you can choose from:
+Finally, if a line is empty or starts with '#' it will be considered
+a comment and not read as a rule. You can use this to better organize
+your override.txt files.
