[esp-zigbee-sdk] Proper way to develop for zigbee devices

[cassianocampes]

I am trying to find a proper documentation or tutorials, etc, that has a good understanding on how to develop using Zigbee technology.
ESP has some documentation like [here](https://docs.espressif.com/projects/esp ... oping.html#), but it does not explain the correct flow when developing using the esp-zigbee-sdk.

For example, what I would expect is something like this:

(1) to develop a minimal EP device, what you should do is...
(2) to develop a Coordinator that can exchange data with EPs, what you should do is...
(3) to update an attribute on a given EP via the Coordinator, what you should do is...
(4) to update an attribute on the EP and report to the Coordinator, what you should do is...

Sorry for such a general question, but I am trying to find some more documentation on this regard but no success.
