At a glance Evaluate the source, compatibility and permissions of the addendum before you give it access to the server.
Check author and download site
Download from the author's official website or recognized repository. Watch out for websites impersonating popular projects, unofficial “cracks” and archives with unexpected files.
Rate compatibility and activity
Check the Minecraft version, supported engine, required dependent plugins, documentation and release history. No updates do not automatically mean a threat, but increases the risk of incompatibility with the newer server.
Test before installing in the world of production
Make backup and check the plugin at private instance. Watch the console, network connections and files it creates. Give it only the required permissions if the permission system allows you to restrict access.
Prepare a removal plan
Save the version number and plugin settings. If errors occur, stop the server, restore the backup or delete the plugin as instructed by the author. Do not delete its data without backup if they store player progress.
Back up first. Change one thing at a time.
Back up your working files, make a change and check the logs. Changing one thing at a time makes it easier to find the cause of a problem and restore your previous settings.
