Installing the Geyser plugin
First, add the jar file to your plugins
directory. You can find GeyserMC at
https://modrinth.com/plugin/geyser.
This should be enough if you already have bedrock's default port (19132) forwarded or allocated, and you don't want to use floodgate. If you want to use a different port number (for example, on shared hosting) please read on.
