I recommend everyone to use at least 2-4 GB of RAM! (for your server too) to prevent crashes. There are a lot of mods in this pack!
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 (Nuclear Mod-Explosion) or paste the following url into the search box.
Finally, click Install at the bottom right of the launcher after you select Nuclear Mod-Explosion from the list on the left. The launcher will handle everything else!
