Download the latest release from either Spigot or GitHub
After downloading the plugin, drop the JAR file into your /plugins/ folder
If you have multiple servers and want to support all of them, make sure to drop the JAR file in your proxy /plugins/ folder too!
If you want to use a Local (JSON/H2) database with a Proxy, make sure to have a (single) Authentication server as the default server when players join.
Without having a single authentication server, the plugin won't be able to reach the local data in a different server
You can find the translated messages.yml files here!
