Very impressive documentation. I have never used any of the fancier options of Github so I followed your instructions to the letter. I found a couple of minor problems.
Under 3 Add Github Actions to our Fork step 5 you have the URL github.com/lupyuen/pinetime-lab/.github/workflows/simulate.yml and this gives a Not Found. The URL should have /blob/master before /.github. (The link underneath the text is correct).
I received two emails from Github saying "The page build failed for the `master` branch with the following error: No `/docs` folder was found to build GitHub Pages.". Is this normal?
