@adius Nice!

It is confusing, and not really explained very well in the jekyll docs (that I could find anyway).

So perhaps document that both a Gemfile and the _config.yml gems declaration is required? New plugins require additions to both files.

Also maybe worth explaining that bundler is invoked during container startup: I found myself reading the Dockerfile to understand what was going on.

And the problem I had was with gem dependency conflicts that went away when I deleted the Gemfile.lock. So perhaps that’s worth noting in the docs as well, as a troubleshooting thing?

It should be installed already as a dependency of the github-pages gem. You would however need to enable it in your _config.yml like this:

gems:
- jekyll-seo-tag
