 1. Transfer images to offline environment.
 1. Load transferred images into offline Docker registry.
 
-### Example image packager script
+### Using the official GitLab template
+
+GitLab provides a [vendored template](../../ci/yaml/README.md#includetemplate)
+to ease this process.
+
+This template should be used in a new, empty project, with a `gitlab-ci.yml` file containing:
+
+```yaml
+include:
+  - template: Secure-Binaries.gitlab-ci.yml
+```
+
+The pipeline downloads the Docker images needed for the Security Scanners and saves them as
+[job artifacts](../../ci/pipelines/job_artifacts.md) or pushes them to the [Container Registry](../../user/packages/container_registry/index.md)
+of the project where the pipeline is executed. These archives can be transferred to another location
+and [loaded](https://docs.docker.com/engine/reference/commandline/load/) in a Docker daemon.
+This method requires a GitLab Runner with access to both `gitlab.com` (including
+`registry.gitlab.com`) and the local offline instance. This runner must run in
+[privileged mode](https://docs.gitlab.com/runner/executors/docker.html#use-docker-in-docker-with-privileged-mode)
+to be able to use the `docker` command inside the jobs. This runner can be installed in a DMZ or on
+a bastion, and used only for this specific project.
+
+#### Scheduling the updates
+
+By default, this project's pipeline will run only once, when the `.gitlab-ci.yml` is added to the
+repo. To update the GitLab security scanners and signatures, it's necessary to run this pipeline
+regularly. GitLab provides a way to [schedule pipelines](../../ci/pipelines/schedules.md). For
+example, you can set this up to download and store the Docker images every week.
+
+Some images can be updated more frequently than others. For example, the [vulnerability database](https://hub.docker.com/r/arminc/clair-db/tags)
+for Container Scanning is updated daily. To update this single image, create a new Scheduled
+Pipeline that runs daily and set `SECURE_BINARIES_ANALYZERS` to `clair-vulnerabilities-db`. Only
+this job will be triggered, and the image will be updated daily and made available in the project
+registry.
+
+#### Using the secure bundle created
+
+The project using the `Secure-Binaries.gitlab-ci.yml` template should now host all the required
+images and resources needed to run GitLab Security features.
+
+The next step is to tell the offline instance to use these resources instead of the default ones on
+`gitlab.com`. This can be done by setting the right environment variables:
+`SAST_ANALYZER_IMAGE_PREFIX` for SAST analyzers, `DS_ANALYZER_IMAGE_PREFIX` for Dependency Scanning,
+and so on.
+
+You can set these variables in the project's `.gitlab-ci.yml` files by using the bundle directly, or
+in the GitLab UI at the project or group level. See the [GitLab CI/CD environment variables page](../../ci/variables/README.md#creating-a-custom-environment-variable)
+for more information.
+
+#### Variables
+
+The following table shows which variables you can use with the `Secure-Binaries.gitlab-ci.yml`
+template:
+
+| VARIABLE                                  | Description                                   | Default value                     |

+| `SECURE_BINARIES_ANALYZERS`               | Comma-separated list of analyzers to download | `"bandit, brakeman, gosec, and so on..."` |

+| `SECURE_BINARIES_PUSH_IMAGES`             | Push files to the project registry            | `"true"`                          |
+| `SECURE_BINARIES_SAVE_ARTIFACTS`          | Also save image archives as artifacts         | `"false"`                         |
+| `SECURE_BINARIES_ANALYZER_VERSION`        | Default analyzer version (docker tag)         | `"2"`                             |
