In the rules Play testers are not a part of the team and can be credited if you want but for coders is assume they count towards the Team because they put work into the game so

Hello!
As we previously said, playtesters are not counted as part of the team. You are free to share the game around with family and friends for further feedback before the jam period ends. However, I do not mainly understand the assistance for things like programming. What do you exactly mean by that, can you give an example?

Cheers.
