I recently got interested in making a galacticraft add-on, but need help with setting up forge with GC API. Sorry if this is the wrong place for this type of post, but I don't know any other forum where I can ask for help.
That would be the support forum, for now you can probably start here though: https://github.com/micdoodle8/Galacticraft
There are some links that should help (some for GC3, but I don't think it will matter as it should be the same)
