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 (pixelmon with my lazy guys) or paste the following url into the search box.
Finally, click Install at the bottom right of the launcher after you select pixelmon with my lazy guys from the list on the left. The launcher will handle everything else!
