Oxide/uMod is used when a server needs plugins, commands, permissions, economy, automation and extra gameplay systems. Before installing, back up the server files and make sure the server is stopped.
After downloading the uMod build, files are usually copied over the Rust server folder. Avoid mixing unknown old files and do not add a full plugin pack before the first startup test.
The first test is simple: start the server, wait for oxide or carbon folders, check the console for errors and then add one basic plugin to confirm loading.
