To install simply drop the MagicalSpells.jar into the plugins folder then start the server.

To update download the latest MagicalSpells.jar then drop it into the plugins folder and override the old one, then to update the config delete the current one (or rename it if you want to keep the custom changes), then start the server and it will create a new updated config, then if you want copy the custom settings over from the old config to the new one.
