# Initialization

How the plugin is initialized at Runtime

The Skins plugin goes through a series of steps to load all the used assets. There are two processes involved through the lifecycle of the game:

1. Plugin Initialization — Performed once at plugin startup
2. Skins Reload — Performed when the user requests a skin reload
