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 (Counter-Craft 3) or paste the following url into the search box.
Finally, click Install at the bottom right of the launcher after you select Counter-Craft 3 from the list on the left. The launcher will handle everything else!
