I expect this to require changes to the theme -- opened #32.

I wanted to try it out / join in on the fun, so here's my attempt: https://github.com/MDAnalysis/MDAKits/pull/61 - merged

I've opened https://github.com/MDAnalysis/distopia/pull/146 for distopia.

It's unclear if they want to be under MDA branding or not, so I've handed it over to Hugo.
