The overall steps are pretty good, but depending on your product and market they may be less or more important (or maybe completely irrelevant).
Honestly my advice would be to jump head-first into it, and learn as you go. Some up-front “theoretical” knowledge would be nice to avoid completely screwing up, and lots of other folks have linked to good reading material for that, but it’s a high risk and ambiguous environment where “best practices” don’t always apply. IMO your efforts should be focused obsessively on iteratively understanding your product market fit and your customers’ needs, rather than theorizing and trying to figure out up-front if existing advice applies to you or not, obsessing over competitors, etc. Those things can definitely help but should be constant feedback loops based on what you’ve done, and not super hypothetical.
Also prepare yourself for an emotional rollercoaster. That’s the hardest part in my experience, having the grit to keep going despite feeling awful or scared or incompetent (and all at the same time).
