How to create an OTA update for custom AOSP Rom?

Question

We're developing our custom Android ROM and we're interested to provide Over-The-Air (OTA) updates to our clients. Can someone point me a detailed step-to-step on how to create an OTA update for a custom Android Open-Source Project (AOSP)? I've already read the Google documentation but I haven't understood it very well.

PS: at current moment we're able to compile our custom Android OS ROM with success, and flash it to the device with no problem.

Not really the official way, but this project does a similar thing.
