It's just vanilla with forge but it is useful for trying mods before using them in a modpack. Also good for using as a "clean client." I most likely won't update it.
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 (Vanilla with Forge | 1.7.10) or paste the following url into the search box.
Finally, click Install at the bottom right of the launcher after you select Vanilla with Forge | 1.7.10 from the list on the left. The launcher will handle everything else!
