There isn't really much more to it than I already wrote. It's minimal, local, markdown-based, and terminal-friendly. There is some basic customizability (special files to add a footer and/or a header), and that's it.
If you already have SSH set up (e.g. for GitHub), it really just takes a minute to get started, so I'd just give it a try and see whether this is the right thing for you.
