Add link to https://docs.pslab.io/

[marcnause]

Actual Behaviour

The app either does not contain a link to https://docs.pslab.io/ or it is so well hidden that I was not able to find it.

Expected Behaviour

There should be an easy way to discover and visit https://docs.pslab.io/ in order to have access to more documentation than the app alone can offer.

Steps to reproduce it

Open the app and try to find a link to https://docs.pslab.io/.
