- Make sure that you have installed and setup hMod correctly.
- Create a "plugins" folder inside your "bin" folder.
- Copy WorldGuard.jar into "plugins".
- If you do not already use WorldEdit, copy WorldEdit.jar into "plugins" from the WorldEdit download
- Add "WorldGuard" to the "plugins" line of your server.properties file so that it looks like
plugins=WorldGuard(If you have multiple plugins, separate plugin names with commas.)
- Restart your server.
