Overview

As Minecraft has grown, it has attracted a massive community of content creators. This community has put forward incredible work to make Vanilla Minecraft look entirely different. From texture packs to full gameplay overhaul packs, these replace almost every element of Minecraft’s gameplay and content. With this growth has come the need for a way to distribute these modpacks. such as the original modpack that gave birth to ATLauncher when its creator, ‘RyanTheAllmighty’ wished to share his modpack with his Youtube Audience.

Since then, ATLauncher has grown into a widely accessible Multi-platform modpack launcher that is able to easily install modpacks from a wide range of sources while supporting mod authors directly. It also has a number of additional baked-in features such as easy 1-click backup of singleplayer saves, and the ability to install packs directly from Curseforge. So in this guide, we will look at installing ATLauncher and use it to run your favourite modpack.
