+WorldEdit
+=========
+
+WorldEdit is a voxel and block manipulation library for Minecraft. It is
+primarily a library but bindings to Bukkit (included) and SPC (external)
+are available.
+
+Compiling
+---------
+
+Some dependencies are required:
+
+- TrueZip (http://java.net/projects/truezip) provides snapshot reading
+- Bukkit (http://bukkit.org/) is a SMP plugin API
+- Rhino (http://www.mozilla.org/rhino/) provides a JavaScript engine
+- GroupUsers (http://forums.bukkit.org/threads/639/) provides an
+    permission system for Bukkit
+- Permissions (http://forums.bukkit.org/threads/1403/) provides an
+    permission system for Bukkit
+
+For links to downloads, check out
+http://wiki.sk89q.com/wiki/WorldEdit/Development
+
+To compile a .jar, use the Ant build file with the 'jar' target.
+
+    ant jar
+
+Contributing
+------------
+
+We happily accept contributions. The best way to do this is to fork
+WorldEdit on GitHub, add your changes, and then submit a pull request. We'll
+look at it, make comments, and merge it into WorldEdit if everything
+works out.
