Not that trivial, first you need to figure out the list of dependencies
GitLab images come with, then you realize you need 50GiB+ of available
storage a single pipeline (due to all the Docker images pulled / built)
and you also need a decent internet link otherwise various jobs timeout
randomly, then you have to wait 20h+ with a quad-core CPU / 16GiB RAM,
and eventually you realize you lost 3 days of your life to not register
your CC which you'll be forced to give anyway.

Long term maintainers don't realize that because they had the luxury to
open their GitLab account soon enough and are now privileged.

It is unfortunate the project strongly suggest new maintainers to pass
by that hassle and doesn't provide access to project resources instead.

But then I know, while the project has access to FOSS hardware resources
it doesn't have human resources to maintain them so can't use them, back
to square one.

Phil.
