How to install a Modrinth Modpack:

  1. Install the Modpack on your server

    Set your server software to the Modpack you want to use. This will automatically install all included mods and configure the server for that pack.
    Browse Modrinth Modpacks on Aternos

  2. Install the Modrinth App on your PC

    The Modrinth App is the easiest way to install and manage Modpacks on your computer. It's available for Windows and integrates with the Minecraft Launcher.
    Download the Modrinth App

  3. Install the Modpack on your PC

    Open the Modrinth App, create a new instance, search for the pack you want, and click 'Install'.

  4. Start the Modpack

    Make sure no instance of the Minecraft Launcher is already running. Then click "Play" in the Modrinth App, log in to your Minecraft account, and launch the game.

  5. Start your server

    Once the game is fully loaded, go back to the Aternos website and start your server.
    Note: Starting a modded server can take significantly longer than a vanilla server.

  6. Connect to your server

    Use the server IP to connect. Make sure the modpack version on your client matches the one on your server.
