Version 1.2: Use new BiomeProvider instead of deprecated Grid

README.md

@@ -5,14 +5,24 @@ This Minecraft (Spigot) plugin generates an empty world with the given name.
 A small start island will be created where the spawn is.
 
 ## Usage
+### Create empty world with island
 To create a new empty world with a floating island as start point:
 `/create-empty-world <world name>`
 
 To import it into Multiverse:
-`/mv import <world name> normal VoidGenerator`
+`/mv import <world name> normal -g EmptyWorldGenerator`
+
+### Create completely empty world
+With the Multiverse plugin you can also create a completely empty world:
+`/mv create <world name> normal -g EmptyWorldGenerator`
 
 Note, that the world name should not contain whitespace characters.
-	
+
+## Issues
+When the generator could not be found by multiverse, you can also try to use this command to import a world into Multiverse:
+`/mv import <world name> normal VoidGenerator`
+But this command does not register the generator in Multiverse, which can lead to worlds with mixed chunks.
