Seriously, How Do Mods Work? (Destiny)

Looking at the vault on DIM, I have approximately nine hundred thousand, billion, billion, billion, billion, billion, billion mods in my possession. But so far, the game hasn't explained how I can use these things or where. So far, it seems like Rares can't be modified at all, and Legendaries can only modify the elemental damage type. How does this all come together? Is there a website where I can learn more about this stuff? Can anybody here tell me what I can do with them?
