Ask HN: Can you give tips on writing a README for project?

I'm currently finishing up the initial version of my experimental embeddable library designed for creating web applications without a build step. But I'm not sure how to make the repository appealing and successful — something that makes people want to try it out, maybe even contribute or improve it.

So, I'd really appreciate any tips you have on writing a great README or structuring the repo — or pointing out any common mistakes I might have made along the way.
