Since a manual installation is a lot of work and error prone we strongly recommend the fast and reliable [Omnibus package installation](https://about.gitlab.com/downloads/) (deb/rpm).
Since 2011 a minor or major version of GitLab is released on the 22nd of every month. Patch and security releases come out when needed. New features are detailed on the [blog](https://about.gitlab.com/blog/) and in the [changelog](CHANGELOG). For more information about the release process see the release [documentation](https://gitlab.com/gitlab-org/gitlab-ce/tree/master/doc/release). Features that will likely be in the next releases can be found on the [feature request forum](http://feedback.gitlab.com/forums/176466-general) with the status [started](http://feedback.gitlab.com/forums/176466-general/status/796456) and [completed](http://feedback.gitlab.com/forums/176466-general/status/796457).
For updating the the Omnibus installation please see the [update documentation](https://gitlab.com/gitlab-org/omnibus-gitlab/blob/master/doc/update.md). For manual installations there is an [upgrader script](doc/update/upgrader.md) and there are [upgrade guides](doc/update).

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).
