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 (COVID-19 Break Pack) or paste the following url into the search box.
Finally, click Install at the bottom right of the launcher after you select COVID-19 Break Pack from the list on the left. The launcher will handle everything else!
