+TODO: A distinct image is still missing. Right now, it looks like a steel axe!
+
 This tool is helpful for creative purposes (i.e. build a wall and "paint" windows into it).
+It replaces nodes with a previously selected other type of node (i.e. places said windows
+into a brick wall).
 
-There is no craft_receipe yet. Use /giveme replacer:replacer
+Crafting:   (nothing) stick (nothing)
+            (nothing) stick (nothing)
+            (nothing) empty_bucket (nothing)
+Or just use /giveme replacer:replacer
 
 Usage: Right-click on a node of that type you want to replace other nodes with.
        Left-click (normal usage) on any nodes you want to replace with the type you previously right-clicked on.
+
+When in creative mode, the node will just be replaced. Your inventory will not be changed.
+
+When not in creative mode, digging will be simulated and you will get what was there. In return, the replacement node
+will be taken from your inventory.
