Homer homepage edit file where is the right config.yaml

I feel my question is simple but I honestly have been trying to work this for a while and can’t figure this out. I have looked for the config files for Homer to edit the homepage to no avail in the root folder, var folder, and have not been able to find it. I have edited the config.yml files and config.yml.dist files.
Am I missing something? The page doesn’t change even after a restart of services or the Pi itself.

did you already have a look to our online docs? System Statistics and Management Options - DietPi.com Docs

There is a section on how to configure.
