How do the different #card types work?

I’ve been making flashcards today. I came across some documentation that showed there was a slash command (/cards…) for adding the card tag. When I tried it, I found 4 card types

  • Card (Forward)
  • Card (Reversed)
  • Card (Incremental)
  • Card (Bidirectional)

Is there any documentation on these types or how to actually use them?
