How to install Mig's Modpacks ?

To install the modpacks, you need the TwitchApp with Minecraft installed on the app. After installing all that stuff, go to "browse modpacks" and search one of my packs.

But... how to install one of my modpacks with MultiMC ? As simple as with the TwitchApp. Install MultiMC, create an instance, go to import from zip and now, go to my modpack page for example Beyond The Skies, go to "Files", install the latest one by clicking on it and downloading it by the button, return to MultiMC, click "browse" button, find this file, and you will be supposed to have that : .

So, you can now install the modpack with MultiMC and everything is OK !
