I’m not a programmer, so I can’t really do it myself. Is it allowed for me to go to some random dude, pay him 20 bucks to write the code, then have him add it to the GitHub?
(If you’re wondering what the app/feature is, I want to be able to shuffle play on the findroid app like you would be able to on the jellyfin web interface )
For an open source project you are welcome to fork it (make a copy for yourself) and modify it however you like. The changes will be only on your fork.
You can also request that the original project pull your changes, in which case it would be available to everyone using it.
