Congratulations on following my tutorial at How to make a Server from a Pack.
Now you want to distribute this server on the Internet so that other people can use it.
This is so easy, you’re gonna probably want to smack your knee or punch a wall!
That server you made, that is fully running now?
Move the world folder out of it.
Then zip it up.
Rename the zip to match the version of the client it works with and upload it to CurseForge attached to the Mod Pack (1) you made as an additional file (2).
Oh and move your world file back after you are done for obvious reasons.
