Merge #785 Add docker and docker-compose installation information

Docker and docker-compose rpms have changed in Fedora 41 in ways that
may be confusing. This document identifies the rpms that comprise the
docker stack and describes some of the changes. Instructions are
provided to achieve common outcomes. RPM names are compared to the names
provided directly by the Docker community. Supplement information on
Podman is also provided.

+== Overview
+
+This guide provides useful information about installing link:https://www.docker.com/[Docker] and Docker-Compose using rpms available from Fedora.
+The role of Podman and related packages is also discussed.
+
+The Docker community also provides rpms for Fedora. For instructions on how to install these rpms please see link:https://docs.docker.com/engine/install/fedora/[Install Docker Engine on Fedora].
+
+[[sect-what-is-docker]]
+=== What is Docker?
+
+link:https:/docker.io[Docker] accelerates "how you build, share, and run applications" by providing an easy to use and configure mechanism to develop and run containers.
+
+This guide is primarily  focused on the Docker rpms available from Fedora and using `dnf` and the command line to install these rpms on Fedora.
+
+[[sect-what-is-docker-compose]]
+=== What is Docker-Compose?
+
+link:https://docs.docker.com/compose/[Docker-Compose] (referred to as Compose below) is software that enables users to easily manage multi-container applications or multiple applications on a single instance of Docker.
+
+Version 1 of Compose was deployed as a stand-alone application called `docker-compose`.
+Version 2 (the current version) is available as a plug-in to the `docker` command and launched as `docker compose [options]`.

+[[sect-fedora-41]]
+== Docker on Fedora 41 (and newer)
+
+The Docker related rpms in Fedora 41 and newer are listed in the table below.
+The corresponding rpm names from the Docker community are also listed for comparison.
+Mixing rpms from Docker with Fedora provided rpms is not recommended and may be blocked by `dnf`.
