I appreciate the effort, but after spending more than one hour on it, I still don't understand how and why I'd use this.

The Core architecture [1] documentation is given in terms of TypeScript or Python abstractions, adding a lot of unnecessary syntactic noise for someone who doesn't use these languages. Very thin on actual conceptual explanation and full of irrelevant implementation details.

The 'Your first server'[2] tutorial is given in terms of big chunks of python code, with no explanation whatsoever, eg:
