This walkthrough documents how mods and plugins are installed on a GameHostCloud server using the built-in mod browser. The first step is confirming which server software is running, because plugins built for Paper, Spigot or Purpur load from the plugins directory while Fabric, Forge, NeoForge and Quilt mods load from the mods directory and the two are not interchangeable. The Mods tab in the dashboard searches Modrinth and CurseForge directly, filters results by the exact game version and loader the server runs, and installs the selected file into the correct directory without any manual upload. After installation the server must be restarted so the loader registers the new content, and the console output should be checked for load errors, missing dependencies or version warnings. Plugins that require a permissions backend, such as LuckPerms, are installed the same way and configured from the console once running. Files that are not available in either catalog can be uploaded manually through the File Manager into the same directory. Common failure modes include installing a plugin on a Fabric server, mismatched Minecraft versions, missing library dependencies and clients being asked to install matching client-side mods; each of these is visible in the console log immediately after a restart.
