@tomasz-torcz-airspace-intelligence this is looking good. It appears to be missing the documentation generation for the changes and it would be nice to see some testing around it; but documentation changes at a minimum: make docs.

Hey, I've regenerated the docs.
Unfortunately, I'm not skilled enough to add tests for that.
