I have deleted solder and moved to a ZIP archive, as the only thing solder was hosting was this pack.
Aetherum was updated to version 1.0.0 3 years ago
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 (Aetherum) or paste the following url into the search box.
Finally, click Install at the bottom right of the launcher after you select Aetherum from the list on the left. The launcher will handle everything else!
