What do you mean with the first suggestion? We have a Bitbucket importer already, I'm not sure if it works with Gh repo's though.

the free private repo information only available on homepage and sign in page. usually what i'm doing is look at the price plan and then find word free or zero dollar

I think you're looking at the price plan page of an on-premises installation https://about.gitlab.com/pricing/ If you search for free on that page you'll find GitLab CE and "Sign up for our free GitLab.com service if you want to use GitLab without installing it."

gitlab only import bitbucket git type, not mercurial type. need workaround, convert from hg to git, then import to gitlab

OK, thanks for the info, feel free to contribute docs for that.
