The Repo for the PvP & SMP Modpack.
You can find the Modpack on Modrinth.
Note, that this Project is currently in Beta so bugs may appear!
First you should download the File. You can do that here or on Modrinth. Currently only ATLauncher, MultiMC and Prism Launcher are supported but in the Future there will be a official Modrinth Launcher.
