How can I make global skill-based matchmaking system with MemoryStoreService

Hello Devs! I was wondering how I can make a Skill-Based Global Matchmaking System using MemoryStoreService. I know the basics to MemoryStoreService but not too much. I can’t really find any tutorials or topics about a skill-based global matchmaking system with MemoryStoreService so I resorted to the place I’m most familiar with!
