Installing a modpack using the Technic Launcher is easy. If you don't already have the launcher downloaded, visit our download page to get the latest version.
Type in the modpack name (Clean Forge for 1.12.2) or paste the following url into the search box.
Finally, click Install at the bottom right of the launcher after you select Clean Forge for 1.12.2 from the list on the left. The launcher will handle everything else!
This really isn's a modpack. It's a simple way to try out some mods on your own.
Just go to the modpacks folder after you've run this once and you'll see that the mods-folder is there, but it's empty. Just fill it with the mods you'd like to try and see if it works. If not, edit configs and try again.
I have this mainly for my own sake, trying out different mods or for trying some things on future modpacks.
