LGTM with a minor change.

Someone familiar with this training's technical details should review before merging.

I just noticed that the two test failures are from redirects in links.

• https://github.com/plone/training/runs/7249210720?check_suite_focus=true#step:5:3035
• https://github.com/plone/training/runs/7249210720?check_suite_focus=true#step:5:3082

I could either fix them in a separate PR and you can merge main into your branch, or you can fix them as part of this PR. Please let me know. Thank you!

Thanks for caring!
With the figure brought back, I will approve.

I would like to keep the figure.

[mliebischer]

Oops, the figure was accidentally deleted.

It was just a tempoararily broken link: https://github.com/plone/training/runs/7249210720?check_suite_focus=true#step:5:3086
With a re-run of the test it's fine now.

Just ping us on Discord channel "documentation" https://discord.com/channels/786421998426521600/862642144401031188 if an unrelated test failure happens.

A re-run of tests can be done by heading over to tab "actions" and restart failed tests like the linkcheck.

[stevepiercy]

Oh, that's right. We don't run linkcheckbroken with it erroring it out on either broken or redirect, like we do in plone/documentation. Maybe we should?

In any case, those two redirect links must be fixed, either in this PR or another.

Done in #627.

@mliebischer once you restore the figure, we can merge. Thank you!
