I just wanted to advertise that it is now possible to see rendered previews of documentation changes (haddocks/user guide/etc) on Gitlab pipelines.

To access this you need to:

1. Wait for a pipeline to complete.

2. From the MR page, click on "Expand" under the pipeline widget, then "Documentation Preview"

3. This takes you to the job artefacts. Then open `docs/index.html`.

4. Gitlab will then redirect you to the hosted page.

Alternatively instead of (2) you can open the "docs-tarball" job directly and click on "Browse" to go to the artefacts.

I've also attached a screen recording to make it a bit clearer.

I actually set this up a few weeks ago in !12415. But I forgot to advertise this more widely at the time. And Gitlab isn't super helpful in directing users to it. So, I realised most folks probably don't know it exists.

Cheers,

Teo
