# Installing Any ATLauncher Modpack
This guide explains how to install any ATLauncher modpack onto your server.
- Ensure you have ATLauncher installed on your computer. If you don't, you can install it at: https://www.atlauncher.com/downloads
- Open ATLauncher on your computer and locate the modpack you wish to install.
- Select "Create Server" for the modpack you wish to install.
- Select the version of the modpack you wish to install (usually the latest version). This must match the version of the modpack you have installed on your computer.
- Select any additional mods you wish to install. If you're unsure, we recommend choosing either "Select Recommended", or none. Once you have selected the mods, click "Install".
- Once the modpack files have finished downloading to your computer, open the directory on your computer where ATLauncher is installed, and then open the "Servers" directory. In this directory, find the server folder you just created and open it. You should now be looking at a folder that contains all of your modpack files.
- Rename the "forge-1.12.2-14.23.1.2566-universal.jar" (or similarly named) file to "custom.jar".
- On your control panel, navigate to the Files tab and upload the contents of the mods directory (not the directory itself) to the base directory of your server
The .bat and .sh files can be deleted as they are not required.
- Change your server's ‘Server Type’ to Custom JAR. We have a guide on this here.
- Start your server and you're all done running your ATLauncher modpack of choice. To connect in-game, ensure you're running the same version of the modpack on your computer through ATLauncher.
