HA Master/Slave


I’m tired of trying to go around and search for any successful documentation around having multiple ha’s with a master/slave configuration.
Can you please just delete the documentation and not trick people into saying that it works and make them lose several hours attempting to do so?
It’s really annoying following documentation that clearly doesn’t work so that in the end I can’t do one of the crucial functionalities on my project that for start was what made me choose HA in the first place.

Or at least if anyone did manage to do it, please update the documentation or create a tutorial.
