 Docker Hub provides a variety of Docker-supported and endorsed images known as Docker Trusted Content. These provide fully managed services or great starters for your own images. These include:
 
 - [Docker Official Images](https://hub.docker.com/search?badges=official) - a curated set of Docker repositories, serve as the starting point for the majority of users, and are some of the most secure on Docker Hub
+- [Docker Hardened Images](https://hub.docker.com/hardened-images/catalog) - minimal, secure, production-ready images with near-zero CVEs, designed to reduce attack surface and simplify compliance. Free and open source under Apache 2.0
 - [Docker Verified Publishers](https://hub.docker.com/search?badges=verified_publisher) - high-quality images from commercial publishers verified by Docker
 - [Docker-Sponsored Open Source](https://hub.docker.com/search?badges=open_source) - images published and maintained by open-source projects sponsored by Docker through Docker's open source program
 
-For example, [Redis](https://hub.docker.com/_/redis) and [Memcached](https://hub.docker.com/_/memcached) are a few popular ready-to-go Docker Official Images. You can download these images and have these services up and running in a matter of seconds. There are also base images, like the [Node.js](https://hub.docker.com/_/node) Docker image, that you can use as a starting point and add your own files and configurations.

 To share your Docker images, you need a place to store them. This is where registries come in. While there are many registries, Docker Hub is the default and go-to registry for images. Docker Hub provides both a place for you to store your own images and to find images from others to either run or use as the bases for your own images.
 
+When choosing base images, Docker Hub offers two categories of trusted, Docker-maintained images:
+
+- [Docker Official Images (DOI)](/manuals/docker-hub/image-library/trusted-content.md#docker-official-images) – Curated images for popular software, following best practices and regularly updated.
+- [Docker Hardened Images (DHI)](/manuals/dhi/_index.md) – Minimal, secure, production-ready images with near-zero CVEs, designed to reduce attack surface and simplify compliance. DHI images are free and open source under Apache 2.0.

 In [Develop with containers](develop-with-containers.md), you used the following images that came from Docker Hub, each of which are [Docker Official Images](/manuals/docker-hub/image-library/trusted-content.md#docker-official-images):
 
 - [node](https://hub.docker.com/_/node) - provides a Node environment and is used as the base of your development efforts. This image is also used as the base for the final application image.
 - [mysql](https://hub.docker.com/_/mysql) - provides a MySQL database to store the to-do list items
 - [phpmyadmin](https://hub.docker.com/_/phpmyadmin) - provides phpMyAdmin, a web-based interface to the MySQL database
 - [traefik](https://hub.docker.com/_/traefik) - provides Traefik, a modern HTTP reverse proxy and load balancer that routes requests to the appropriate container based on routing rules
