Thank you for bringing this up @devel-pa . Going to take a crack at it today.

[devel-pa]

Wow, super fast 😄
One extra question, pls: there is any architecture page in the docs to explain how this thing works?
Thanks,

Paul

[diego-escobedo]

These are the different components of the architecture! Don't have any section in the docs for it right now
