+##Schematic on Claim
+The schematic on claim option is quite strange, and might be hard to understand. Therefore I've decided to create this simple guide that will teach you how to use that powerful feature of PlotSquared. 
+
+ 1. Make sure you have a schematic the exact size of your plots (if you have the plot width set to 32 blocks, then the schematic must be exactly 32x32 blocks big). I would advice you to use WorldEdit to save the schematic. 
+
+ Select the plot area (from the floor and up) Type `//copy` When you have the selection copied, you can save it with `//schematic save mce {schematic_name}` 
+
+ 2. When you have the `.schematic` file, place it in `/plugins/PlotSquared/schematics`, if the folder doesn't exists then you'll have to create it. 
+
+ 3. To validate the schematic type `/plot schematic test {schematic_name}`. You can now test if it pastes successfully using `/plot schematic paste {schematic_name}` 
+
+ Now you have a working schematic file. To have it paste on claim you'll need to configure your settings.yml, here is a simple snippet explaining how to do that. 
+```YAML
+# The following is a slice from the plotworld settings, change this for each plotworld
+schematic:
+    # File name (without .schematic)
+	file: '{schematic_name}' 
+	# If you want it on claim
+	on_claim: true`
+```
+You can use the same schematic for more than one plotworld.

+##AdvPlot Generator
+The AdvPlot generator is a custom generator (still in development) Please see the project page for more information on this generator 
+##Plot Merging
+Plot merging is simple. With the default generator, you can either have automatic plot merging, or manual. 
+
+Automatic plot merging can be set through the `settings.yml` 
+The command to manually merge plots is: `/plots merge {direction}` where `{direction}` is the direction you wish to merge
