Good in-depth guides for starting a podcast?

I’ve been slowly working my way towards starting a podcast. I know my theme and I have ideas for the first couple episodes, but I’m looking for more in-depth guides through the technical parts of the process. I can research and find open source audio editors, I have access to a good mic setup, and I can write a script, record it, and edit it. My concern is more of the release side. I’m aware that the podcast ecosystem runs via RSS, but I’m looking for a sort of walkthrough of this last leg of the process. Any suggestions are welcome. Thanks!
