How to make a item collection datastore that tells you what you have?

Hello! I am currently trying to make a feature in a game that is like a index. The index shows a description and title, but only is visible when you collect the item. I have literally nowhere to start because there isn’t a single tutorial at all and I have been searching on the devforum and have gotten nothing.

I was thinking I could make a system that adds bool values per collectable that auto updates but I don’t even know where to start honestly. Any leads?
