 ### Gitlab
 
+#### Creating a GitLab OAuth application
+
+Follow this link, [Add new application](https://gitlab.com/-/profile/applications).
+
+1. Set Application Name to `backstage-dev` or something along those lines.
+1. The Authorization Callback URL should match the redirect URI set in Backstage.
+   1. Set this to `http://localhost:7000/api/auth/gitlab/handler/frame` for local development.
+   1. Set this to `http://{APP_FQDN}:{APP_BACKEND_PORT}/api/auth/gitlab/handler/frame` for non-local deployments.
+   1. Select the following scopes from the list:
+      - [x] `read_user` Grants read-only access to the authenticated user's profile through the /user API endpoint, which includes username, public email, and full name. Also grants access to read-only API endpoints under /users.
+      - [x] `read_repository` Grants read-only access to repositories on private projects using Git-over-HTTP (not using the API).
+      - [x] `write_repository` Grants read-write access to repositories on private projects using Git-over-HTTP (not using the API).
+      - [x] `openid` Grants permission to authenticate with GitLab using OpenID Connect. Also gives read-only access to the user's profile and group memberships.
+      - [x] `profile` Grants read-only access to the user's profile data using OpenID Connect.
+      - [x] `email` Grants read-only access to the user's primary email address using OpenID Connect.
+
 ```bash
-export GITLAB_BASE_URL=x # default is https://gitlab.com
-export AUTH_GITLAB_CLIENT_ID=x
+export GITLAB_BASE_URL=https://gitlab.com
+export AUTH_GITLAB_CLIENT_ID=x  # Gitlab calls this the Application ID
+export AUTH_GITLAB_CLIENT_SECRET=x
+```
+
+#### Creating a GitLab Enterprise OAuth application
+
+If you have GitLab Enterprise, perform the steps above, replacing `gitlab.example.com` in the following
+with the domain of your GitLab Enterprise host:
+
+Create new application at: `https://gitlab.example.com/profile/applications`.
+
+```bash
+export GITLAB_BASE_URL=https://gitlab.example.com
+export AUTH_GITLAB_CLIENT_ID=x  # GitLab calls this the Application ID
 export AUTH_GITLAB_CLIENT_SECRET=x
 ```
