Modrinth vs AT-Launcher

You will need to download either the Modrinth or AT Launcher to run this modpack.

The TLDR:

Choose the AT-Launcher if you are planning to have multiple instances, multiple accounts, or run mod-packs with Curse Forge mods. Otherwise, the Modrinth Launcher should be great.

Modrinth Launcher

The modpack will be posted on the Modrinth website, so the Modrinth Application will be the simplest way to run the mod-pack.

AT-Launcher:

The AT-Launcher is my preferred Launcher, because it can run both Curse Forge & Modrinth packs. It provides more flexibility than the Modrinth application. The AT-Launcher can also create & run server instances.
