Administrator Docs (CORE ONLY)
Learn how to administer your self-managed GitLab instance.

You can install either GitLab CE or GitLab EE. However, the features you'll have access to depend on the subscription you choose (Core, Starter, Premium, or Ultimate).
NOTE: Note: GitLab Community Edition installations only have access to Core features.
GitLab.com is administered by GitLab, Inc., therefore, only GitLab team members have access to its admin configurations. If you're a GitLab.com user, please check the user documentation.
