FLAG:
On self-managed GitLab, by default this feature is available. To hide the feature, ask an administrator to [disable the feature flag](../administration/feature_flags.md) named `sourcegraph`.
On GitLab.com, this feature is available for public projects only.
If you are new to Sourcegraph, head over to the [Sourcegraph installation documentation](https://docs.sourcegraph.com/admin) and get your instance up and running.
If you are using an HTTPS connection to GitLab, you must [configure HTTPS](https://docs.sourcegraph.com/admin/http_https_configuration) for your Sourcegraph instance.
### Connect your Sourcegraph instance to your GitLab instance
1. Navigate to the site admin area in Sourcegraph.
1. [Configure your GitLab external service](https://docs.sourcegraph.com/admin/external_service/gitlab).
You can skip this step if you already have your GitLab repositories searchable in Sourcegraph.
1. Validate that you can search your repositories from GitLab in your Sourcegraph instance by running a test query.
1. Add your GitLab instance URL to the [`corsOrigin` setting](https://docs.sourcegraph.com/admin/config/site_config#corsOrigin) in your site configuration.
### Configure your GitLab instance with Sourcegraph
If you enabled Sourcegraph for your project but it isn't working, Sourcegraph may not have indexed the project yet. You can check for Sourcegraph's availability of your project by visiting `https://sourcegraph.com/gitlab.com/<project-path>`replacing `<project-path>` with the path to your GitLab project.
