+# Gitlab-CI Configuration
+
+When using your own gitlab instance, the provided .gitlab-ci.yml will be automatically be using the settings provided by the Gitlab Instance. If needed several options can be overriden.
+
+Overrides for these values can be set within the project, under `Settings` -> `CI/CD` -> `Variables`.
+
+| Variable           | Default Value      | Description                                                                                                                                                                                                             |
+| ------------------ | ------------------ | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
+| `CI_REGISTRY`      | `hub.docker.com`   | If available this will be automatically overriden by registry address which is configured within the Gitlab instance                                                                                                    |
+| `CI_REGISTRY_USER` | `gitlab-ci-token`  | Username for the registry                                                                                                                                                                                               |
+| `CI_REGISTRY_PASS` | `${CI_JOB_TOKEN}`  | Password for the registry                                                                                                                                                                                               |
+| `DOCKER_IMAGE`     | `sameersbn/gitlab` | Docker image name, will be automatically be overriden by the running Gitlan instance with the `${C_PROJECT_PATH}` variable. This will case the image to be uploaded to the local registry of the project within Gitlab. |
