+## Delete images
+
+You can delete images from your Container Registry in multiple ways.
+
+CAUTION: **Warning:**
+Deleting images is a destructive action and can't be undone. To restore
+a deleted image, you must rebuild and re-upload it.
+
+NOTE: **Note:**
+Administrators should review how to
+[garbage collect](../../../administration/packages/container_registry.md#container-registry-garbage-collection)
+the deleted images.
+
+### Delete images from within GitLab
+
+To delete images from within GitLab:
+
+1. Navigate to your project's or group's **{package}** **Packages > Container Registry**.
+1. From the **Container Registry** page, you can select what you want to delete,
+   by either:
+
+   - Deleting the entire repository, and all the tags it contains, by clicking
+     the red **{remove}** **Trash** icon.
+   - Navigating to the repository, and deleting tags individually or in bulk
+     by clicking the red **{remove}** **Trash** icon next to the tag you want
+     to delete.
+
+1. In the dialog box, click **Remove tag**.
+
+   ![Container Registry tags](img/container_registry_tags_v12_10.png)
+
+### Delete images using the API
+
+If you want to automate the process of deleting images, GitLab provides an API. For more
+information, see the following endpoints:
+
+- [Delete a Registry repository](../../../api/container_registry.md#delete-registry-repository)
+- [Delete an individual Registry repository tag](../../../api/container_registry.md#delete-a-registry-repository-tag)
+- [Delete Registry repository tags in bulk](../../../api/container_registry.md#delete-registry-repository-tags-in-bulk)
+
+### Delete images using GitLab CI/CD
+
+CAUTION: **Warning:**
+GitLab CI/CD doesn't provide a built-in way to remove your images, but this example
+uses a third-party tool called [reg](https://github.com/genuinetools/reg)
+that talks to the GitLab Registry API. You are responsible for your own actions.
+For assistance with this tool, see
+[the issue queue for reg](https://github.com/genuinetools/reg/issues).
+
+The following example defines two stages: `build`, and `clean`. The
+`build_image` job builds the Docker image for the branch, and the
+`delete_image` job deletes it. The `reg` executable is downloaded and used to
+remove the image matching the `$CI_PROJECT_PATH:$CI_COMMIT_REF_SLUG`
+[environment variable](../../../ci/variables/predefined_variables.md).
+
+To use this example, change the `IMAGE_TAG` variable to match your needs:
+
+```yaml
+stages:
+  - build
+  - clean
+
+build_image:
+  image: docker:19.03.1

+
+TIP: **Tip:**
+You can download the latest `reg` release from
+[the releases page](https://github.com/genuinetools/reg/releases), then update
+the code example by changing the `REG_SHA256` and `REG_VERSION` variables
+defined in the `delete_image` job.
+
+### Delete images using an expiration policy
+
+You can create a per-project [expiration policy](#expiration-policy) to ensure
+older tags and images are regularly removed from the Container Registry.
+
