I think the preview action is trying to push to Islandora/documentation, but as me? https://github.com/Islandora/documentation/actions/runs/5245070365/jobs/9471983399?pr=2240#step:4:198

Then it gives some other error https://github.com/Islandora/documentation/actions/runs/5245070365/jobs/9471983399?pr=2240#step:4:268

@whikloj :

Just, rationale for the "preview" thing having failed: https://github.com/rossjrw/pr-preview-action

This Action does not currently support deploying previews for PRs from forks, but will do so in rossjrw/pr-preview-action#6.

Ohhhh so I should have opened this from the documentation repo. I'll try to remember that in the future.

I was just trying a pull request from my fork to see if that was the reason, but now I see that it was confirmed as the reason. At least it gave me an excuse to create a PR I had been meaning to create.

Looks great. I got to the bottom of the file and things worked. The only error I got was that comments in the fcrepo.properties file aren't valid, so I made a PR with a small warning to take them out. whikloj#1

I will admit I haven't finished the manual install instructions, but this page seems good to go (with the small addition above).

Hey @rosiel, sorry about that. I moved the comments to their own lines. I can still merge your addition, but this allows the copy block to work.
