-We only show, how you register the placeholders, when you have the class in your own plugin.

-A complete explanation of the PlaceholderExpansion and how to create own placeholders/expansions with it is explained [[here|Creating Placeholders using Expansions]] in more detail.

-Just register your class like you do with the [EZPlaceholderHook](#ezplaceholderhook-deprecated), but instead of using `.hook()` you use `.register()` to register the class.
