Resourcepack first installation
Before using the plugin you have to decide the resourcepack hosting method. Read this tutorial to decide the hosting method for the resourcepack. The best method is simple_self_host.
(recommended) Install ItemsAdderAdditions
ItemsAdderAdditions is a plugin that adds new features, actions, behaviours. You can download on Modrinth or SpigotMC
(optional) Add official ItemsAdder custom content
ItemsAdder comes with a lot of custom content already created for you. It's not automatically included in the downloaded plugin because some people might not want every item/feature automatically added into their server.
