 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

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.
