URL link seems broken
For me it doesn't work to copy the URL from https://gitlab.com/caspermeijn/klok/-/blob/master/docs/installation.md. It redirects to https://gitlab.com/caspermeijn/klok/-/jobs/artifacts/master/raw/bin/targets/klok-pinetime/app/apps/klok/klok.img?job=build but for me that downloads an empty file.
In the end it worked by going to https://gitlab.com/caspermeijn/klok/-/pipelines Maybe the URL link should be updated?
