On all documentation pages the header link is broken.
I didn't understand.. What you meant! Can you please ellaborate?

Circled in the image above, the WET logo links to a page (https://wet-boew.github.io/index-en.html) which doesn't exist.
There is a much large issue. PR sent https://github.com/wet-boew/wet-boew-documentation/pull/231.
