Any updates the Brokerage Development Guide?

[quminhdo]

I would want to connect Lean to a custom brokerage and data provider. I referred to the Brokerage Development Guide (https://github.com/QuantConnect/Tutorials/tree/master/03%20Open%20Source/05%20Brokerage%20Development%20Guide), but it is incomplete and has not been updated for 4 years. Do you plan to update it soon?
