dead link in README
On the current README there is a link to https://gitlab.com/gitlab-org/gitlab-development-kit#development
Instructions on how to start GitLab and how to run the tests can be found in the [development section of the GitLab Development Kit](https://gitlab.com/gitlab-org/gitlab-development-kit#development).
Not sure where correct link is - maybe developer docs page on CE repo. info I was after was https://docs.gitlab.com/ce/development/rake_tasks.html
