+## Prerequisites
+
+To install Docker Desktop successfully, you must:
+
+- Meet the [system requirements](linux-install.md#general-system-requirements).
+- Have a 64-bit version of either RHEL 8 or RHEL 9.
+
+If you don't have `pass` installed, or it can't be installed, you must enable
+[CodeReady Linux Builder (CRB) repository](https://access.redhat.com/articles/4348511)
+and
+[Extra Packages for Enterprise Linux (EPEL)](https://docs.fedoraproject.org/en-US/epel/).

+
+Additionally, for a GNOME desktop environment you must install AppIndicator and KStatusNotifierItem [GNOME extensions](https://extensions.gnome.org/extension/615/appindicator-support/). You must also enable EPEL.
+
+   {{< tabs group="os_version" >}}

+$ sudo gnome-shell-extension-tool -e appindicatorsupport@rgcjonas.gmail.com
+```
+
+   {{< /tab >}}
+   {{< /tabs >}}
+
+For non-GNOME desktop environments, `gnome-terminal` must be installed:
+
+```console
+$ sudo dnf install gnome-terminal
+```
+
+## Install Docker Desktop
+
+To install Docker Desktop on RHEL:
+
+1. Set up Docker's package repository as follows:
+
+   ```console
+   $ sudo dnf config-manager --add-repo {{% param "download-url-base" %}}/docker-ce.repo
+   ```
+
+2. Download latest [RPM package](https://desktop.docker.com/linux/main/amd64/docker-desktop-4.28-x86_64-rhel.rpm?utm_source=docker&utm_medium=webreferral&utm_campaign=docs-driven-download-linux-amd64).
+
+3. Install the package with dnf as follows:
+
+   ```console
+   $ sudo dnf install ./docker-desktop-<version>-<arch>-rhel.rpm
+   ```
+
+There are a few post-install configuration steps done through the post-install script contained in the RPM package.
+
+The post-install script:
+
+- Sets the capability on the Docker Desktop binary to map privileged ports and set resource limits.
+- Adds a DNS name for Kubernetes to `/etc/hosts`.
+- Creates a symlink from `/usr/local/bin/com.docker.cli` to `/usr/bin/docker`.
+  This is because the classic Docker CLI is installed at `/usr/bin/docker`. The Docker Desktop installer also installs a Docker CLI binary that includes cloud-integration capabilities and is essentially a wrapper for the Compose CLI, at`/usr/local/bin/com.docker.cli`. The symlink ensures that the wrapper can access the classic Docker CLI. 
+- Creates a symlink from `/usr/libexec/qemu-kvm` to `/usr/local/bin/qemu-system-x86_64`.
+
+## Launch Docker Desktop
+
+{{< include "desktop-linux-launch.md" >}}
+
+>**Tip**
+>
+> To attach Red Hat subscription data to containers, see [Red Hat verified solution](https://access.redhat.com/solutions/5870841).
+>
+> For example:
+> ```console
+> $ docker run --rm -it -v "/etc/pki/entitlement:/etc/pki/entitlement" -v "/etc/rhsm:/etc/rhsm-host" -v "/etc/yum.repos.d/redhat.repo:/etc/yum.repos.d/redhat.repo" registry.access.redhat.com/ubi9
+> ```
+{ .tip }
+
+## Upgrade Docker Desktop
+
+Once a new version for Docker Desktop is released, the Docker UI shows a notification.
+You need to first remove the previous version and then download the new package each time you want to upgrade Docker Desktop. Run:
+
+```console
+$ sudo dnf remove docker-desktop
+$ sudo dnf install ./docker-desktop-<version>-<arch>-rhel.rpm
+```
+
+## Next steps
+
+- Take a look at the [Get started](../../guides/get-started/_index.md) training modules to learn how to build an image and run it as a containerized application.
+- [Explore Docker Desktop](../use-desktop/index.md) and all its features.
+- Review the topics in [Develop with Docker](../../develop/index.md) to learn how to build new applications using Docker.
