How do you promote the new features of your startup?

I was thinking about this topic because I've built a ton for https://userdesk.io this month.

I put some effort into describing and promoting those features, and I ended up documenting all the effort I made into a single thread on X / Twitter https://twitter.com/ikoichi/status/1716061859034657015

I think this could be a good start to define a small framework to promote our features, and to apply it again in the future.

We are builders, but often we forget that a feature is not 100% done until we clearly communicate its existence.

What's your experience with promoting and documenting your features?
