ATLauncher is a simple, easy-to-use launcher, built around the concept of building game instances from “packs”. To set up your own Quilt instance, simply follow these steps:

1. Download and install ATLauncher from their website
2. Open ATLauncher and click on the Vanilla Packs tab on the right side
3. Fill out the Instance Name and Instance Description boxes as required
4. Pick the version of Minecraft you’d like to use for your instance
5. Pick Quilt from the list of loaders below the Minecraft versions section
6. Select the Quilt Loader version you’d like to use
7. Click Create Instance to create your instance

That’s all there is to it! You can find your new instance in the Instances tab on the right side of the window.

Installing Mods

To install mods to your ATLauncher instance, simply follow these steps:

1. Click on the Instances tab on the right side
2. Find the instance you’d like to add mods to, and click on Add Mods
3. Find a Fabric or Quilt mod from CurseForge or Modrinth, and click the Add button
4. Ensure you have also added the Quilted Fabric API/Quilt Standard Libraries bundle, which you can find on CurseForge or on Modrinth

If you can’t find the mod you’d like to install using the built-in search, you can click on Open Folder and copy any mod files you’d like to use into the mods/ folder.

Start up your game, and the mods should be available immediately. If you run into any issues, please take a look at the troubleshooting page, or join us on Discord to ask for support!
