@mgan59 I think the action won't run because I've proposed from a fork, rather than a direct branch. Can we adjust the action so that works, or is this a limitation of GH Actions?

I might have answered my own question. According to https://github.blog/2020-08-03-github-actions-improvements-for-fork-and-pull-request-workflows/ I need to change the action to run on: [pull_request_target]. Let me try that.

So I've taken so long to review this, that this website repo has become deprecated, replaced by the hugo-website repo.

Lana, if there is anything of value in this pull request, I suggest that you re-apply it to the hugo-website repo.

Sorry for the slow review, and resulting extra work caused. I'll commit to review within a couple of weeks if you redo this in the hugo repo (and tell me of it).

I'll leave it to you Lana to decide whether you want this review approved here as well, but I'd suggest this request should be closed out with no action.

I don't have the time to handle this right now, sorry. Feel free to close it. If someone wants to take these images and add them to the new site, I'm happy for them to do so.

This is a good first time issue for someone who wants to learn how to use git.
Look at these changes that Loquacity has recommended in this legacy repository thegooddocsproject.github.io and copy the changes across to https://github.com/thegooddocsproject/website-hugo
