Forge version

Hello, I would like to know how to install a forge version other than the one that is on MineOS, because my mods do not go with the only version that on MineOS, and I have a lot of mods, so here is my question:
How do I install another version of Forge 1.12.2. where should I go ???

The webui attempts to help users by providing the existing profiles, however, profiles are a convenience, not a necessity.

Profiles put files in the “live” directory (you can see the path from the status page). If the Jarfile and mods are located in the “live” directory, MineOS will use them, rather than any available profile.

TLDR; profiles just places jarfiles in the appropriate directory. If you manually put jarfiles there, it will work, too.
