-   Replacement tool for creative building (Mod for MineTest)
+ ## Replacer Tool
 
-This tool is helpful for creative purposes (i.e. build a wall and "paint" windows into it).
+Replacer tool for creative building in [Minetest](http://minetest.net) is helpful for copying, placing and replacing nodes. The tool can place or replace existing nodes with a previously selected other type of node (i.e. places said windows into a brick wall) preserving rotations of the copied node.
-It replaces nodes with a previously selected other type of node (i.e. places said windows
-into a brick wall).
 
-Crafting:   chest  -      -
+### Crafting the replacer:   
-            -      stick  -
+chest | _____ | _____ 
-            -      -      chest
-Or just use /giveme replacer:replacer
 
-Usage: Right-click on a node of that type you want to replace other nodes with.
+_____ | stick | _____
-       Left-click (normal usage) on any nodes you want to replace with the type you previously right-clicked on.
-       SHIFT-Right-click in order to store a new pattern.
 
-When in creative mode, the node will just be replaced. Your inventory will not be changed.
+_____ | _____ | chest 
 
-When not in creative mode, digging will be simulated and you will get what was there. In return, the replacement node
+### Commands
-will be taken from your inventory.
+Give yourself a replacer (priv required) `/giveme replacer:replacer`
 
+Set replacer modes (paint/legacy) `/replacer legacy` `/replacer paint`
 
-The second tool included in this mod is the inspector.
+### Paint mode controls (default)
+   The controls allow players continuously place or replace nodes by holding down right mouse key (Shift for replace)
 
-Crafting:    torch
+   `Shift + Left Mouse`:  Set replacer's replacement node data (node to be placed)
-             stick
+   
+   `Left Mouse`:          Replace pointed node with replacement node.
+   
+   `Right Mouse`:         Place replacement node on pointed node (normal placement) continuously while keys are held.
+   
+   `Shift + Right Mouse`: Replace pointed node with replacement node continuously while keys are held
+
+### Legacy mode controls
+   `Right Mouse` Place replacement node on pointed face.
+  
+   `Left Mouse`: Replace pointed node with replacement node.
+   
+   `Shift + Right Mouse`: Set replacer's replacement node data (node to be placed)
+
+### Inventory and Creative mode support
+When not in creative mode, digging will be simulated when replacing nodes, giving the player any drops. In return, the replacement node will be taken from your inventory.
+
+When in minetest game's creative mode, the node will just be replaced. Your inventory will not be changed.
+
+## Inspector tool
+   The inspector tool shows information about the pointed node.

 Just wield it and click on any node or entity you want to know more about. A limited craft-guide is included.
