Documentation

Every command, permission and placeholder, written down — along with the parts that actually catch people out.

Start here

Installing a plugin
Stop the server, drop the jar into plugins/, start it again. A reload is not enough for a first install — Bukkit will load the plugin but skip parts of the startup sequence that only run on boot, and the symptoms look like a broken jar.
Your licence key
Every purchase gets one key, shown on your account page. Paste it into the plugin config where the file asks for it. One key covers one network plus its test server; ask in Discord if you run something unusual.
Updating safely
Back up the plugin folder, swap the jar, restart. Config files are migrated forward automatically and new keys are added with their defaults — your edits are never overwritten. Read the changelog before a major version bump.

If the docs did not answer it, that is a gap worth fixing. Ask in Discord — the answer usually ends up in here afterwards.
