@MichaIng, @fpetru: I added you as reviewers to test whether this is the right way we should act when committing to dev branch. Depending on the issue also no reviewer (e.g. typos) or only one reviewer (to fulfil a 4 eyes principle) might be enought.

Great. I made the master branch a protected branch where any pull request requires at least one approved review before it can be merged.

Shall I add a simple method to test the current dev branch or even a choosable owner/branch directly on our server, e.g. dietpi.com/testdocs or similar? This would allow us to test as well the build, so that no Python module is missing and/or no incompatible version installed and possibly webserver related issues. That URL needs to be added to site crawler exclusion (robots.txt) and to Cloudflare cache exclusion. We might even want to add an authentication method to access the testing site.
Uploading/building to that test URL could be as well to allow final test before merging into master, as part of the review procedure?
