Request for Developer Documentation for MIT App Inventor

hello,
I wanted to ask if there is any developer documentation available for MIT App Inventor. It would be incredibly helpful for understanding the system.

Thank you

We have a bunch of documentation spread out across a number of pages. Is there something in particular you are looking for?

I am currently working on the AppEngine section and would like to access documentation related to it. Specifically, I’m looking for details on how the backend and frontend code flow works.

Having such documentation would help me to better understand the codebase but also make it easier for new contributors like me to navigate and comprehend the purpose of each file and its role within the project.
