Ask What are the first steps to setting up a membership site?

[SuperAffiliateX]

I want to start a membership site, but I have no idea where to begin. Do I need special software or a specific platform? Should I focus on building content first or setting up payment options? I don't know what steps to take or what mistakes to avoid. I also want to make sure the site is easy to use for members. I would love some advice from people who have done this before.
