# Administrator documentation **[CORE ONLY]**
|
|
|
|
Learn how to administer your GitLab instance (Community Edition and
|
|
Enterprise Edition).
|
|
Regular users don't have access to GitLab administration tools and settings.
|
|
|
|
GitLab has two product distributions: the open source
|
|
[GitLab Community Edition (CE)](https://gitlab.com/gitlab-org/gitlab-ce),
|
|
and the open core [GitLab Enterprise Edition (EE)](https://gitlab.com/gitlab-org/gitlab-ee),
|
|
available through [different subscriptions](https://about.gitlab.com/pricing/).
|
|
|
|
You can [install GitLab CE or GitLab EE](https://about.gitlab.com/installation/ce-or-ee/),
|
|
but the features you'll have access to depend on the subscription you choose
|
|
(Core, Starter, Premium, or Ultimate). 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](../user/index.html).
