ended up not using

after the first init.

setting options on each startup so that the WebUI is functional

Make clear train switching is not supported

Remove requirements.yaml, due to Helm 3 changes

Helm 3 merges requirements.yaml into Chart.yaml.
I tested this config with the CI and it works fine, it seems only fitting to remove requirements.yaml from the documentation. as it's depricated, every new chart uploaded to the repo should have it copy-pasted into the Chart.yaml (the syntax is still the same)

slight addaption based on slack feedback

Adds a small note about train switching not being supported currently
