Hi! You probably should use #help-and-feedback scripting support category
Profile service is thing that allow u save player stats/data (e.g… coins, gems, inventory). It’s so much better than roblox’s datastore cuz it safer and have some cool features like global updates or etc.
So that’s means u should use helping category, because u asking simple question. U should use discussion cat, when u asking question that will give discussion (for example some problem on roblox)
Learn it when you are professional … Don’t try to learn it if you haven’t learnt the basic concepts yet (Remote functions and events, servers, clients, datastores, player data, etc)
learn datastores and players data, and learn how to deal with instances inside player model, then you can learn it, but don’t expect to master it in a few days.
