It is somewhat confusing, at least to me, that the documentation that shows up when you go to the benchopt website is that of the development version and not of the stable version. Parts of it apply only to the development version, so I think it could be hard for the average user to navigate this.

I suggest to either

1. Just show the documentation for the stable version.
2. Show documentation for both, but with a toggle (as in https://contrib.scikit-learn.org/skglm/stable/getting_started.html)
