To the best of my understanding, I think it’s going to be pieces of code that can be shared with other people. So it wouldn’t be a whole project, but more like a function within that project (maybe the code for a joystick for example). Like the ‘Custom Rules,’ but that can be used in different projects, not just the one it was created in.
If you’ve ever used Scratch, theres a ‘backpack’ function where you can place code inside of it, and then when you make a new project, you can pull the code out of it. I’m thinking it will be similar to this, but with code shared by the community.
If someone else understood differently, let me know (:
