 Available variables are listed below, along with default values (see `defaults/main.yml`):
 
-```yaml
-# Edition can be one of: 'ce' (Community Edition) or 'ee' (Enterprise Edition).
-docker_edition: 'ce'
-docker_packages:
-    - "docker-{{ docker_edition }}"
-    - "docker-{{ docker_edition }}-cli"
-    - "docker-{{ docker_edition }}-rootless-extras"
-docker_packages_state: present
-```
+    TODO.
 
-The `docker_edition` should be either `ce` (Community Edition) or `ee` (Enterprise Edition). 
-You can also specify a specific version of Docker to install using the distribution-specific format: 
-Red Hat/CentOS: `docker-{{ docker_edition }}-<VERSION>` (Note: you have to add this to all packages);
-Debian/Ubuntu: `docker-{{ docker_edition }}=<VERSION>` (Note: you have to add this to all packages).
-
-You can control whether the package is installed, uninstalled, or at the latest version by setting `docker_packages_state` to `present`, `absent`, or `latest`, respectively. Note that the Docker daemon will be automatically restarted if the Docker package is updated. This is a side effect of flushing all handlers (running any of the handlers that have been notified by this and any other role up to this point in the play).
-
-```yaml
-docker_obsolete_packages:
-  - docker
-  - docker.io
-  - docker-engine
-  - docker-doc
-  - docker-compose
-  - docker-compose-v2
-  - podman-docker
-  - containerd
-  - runc
-```
-
-`docker_obsolete_packages` for different os-family:
-
-- [`RedHat.yaml`](./vars/RedHat.yml)
-- [`Debian.yaml`](./vars/Debian.yml)
-
-A list of packages to be uninstalled prior to running this role. See [Docker's installation instructions](https://docs.docker.com/engine/install/debian/#uninstall-old-versions) for an up-to-date list of old packages that should be removed.
-
-```yaml
-docker_service_manage: true
-docker_service_state: started
-docker_service_enabled: true
-docker_restart_handler_state: restarted
-```
-
-Variables to control the state of the `docker` service, and whether it should start on boot. If you're installing Docker inside a Docker container without systemd or sysvinit, you should set `docker_service_manage` to `false`.
-
-```yaml
-docker_install_compose_plugin: true
-docker_compose_package: docker-compose-plugin
-docker_compose_package_state: present
-```
-
-Docker Compose Plugin installation options. These differ from the below in that docker-compose is installed as a docker plugin (and used with `docker compose`) instead of a standalone binary.
-
-```yaml
-docker_install_compose: false
-docker_compose_version: "v2.32.1"
-docker_compose_arch: "{{ ansible_architecture }}"
-docker_compose_url: "https://github.com/docker/compose/releases/download/{{ docker_compose_version }}/docker-compose-linux-{{ docker_compose_arch }}"
-docker_compose_path: /usr/local/bin/docker-compose
-```
-
-Docker Compose installation options.
-
-```yaml
-docker_add_repo: true
-```
-
-Controls whether this role will add the official Docker repository. Set to `false` if you want to use the default docker packages for your system or manage the package repository on your own.
-
-```yaml
-docker_repo_url: https://download.docker.com/linux
-```
-
-The main Docker repo URL, common between Debian and RHEL systems.
-
-```yaml
-docker_apt_release_channel: stable
-docker_apt_arch: "{{ 'arm64' if ansible_architecture == 'aarch64' else 'amd64' }}"
-docker_apt_repository: "deb [arch={{ docker_apt_arch }}{{' signed-by=/etc/apt/keyrings/docker.asc' if add_repository_key is not failed}}] {{ docker_repo_url }}/{{ ansible_distribution | lower }} {{ ansible_distribution_release }} {{ docker_apt_release_channel }}"
-docker_apt_ignore_key_error: True
-docker_apt_gpg_key: "{{ docker_repo_url }}/{{ ansible_distribution | lower }}/gpg"
-docker_apt_filename: "docker"
-```
-
-(Used only for Debian/Ubuntu.) You can switch the channel to `nightly` if you want to use the Nightly release.
-
-You can change `docker_apt_gpg_key` to a different url if you are behind a firewall or provide a trustworthy mirror.
-Usually in combination with changing `docker_apt_repository` as well. `docker_apt_filename` controls the name of the source list file created in `sources.list.d`. If you are upgrading from an older (<7.0.0) version of this role, you should change this to the name of the existing file (e.g. `download_docker_com_linux_debian` on Debian) to avoid conflicting lists.
-
-```yaml
-docker_yum_repo_url: "{{ docker_repo_url }}/{{ (ansible_distribution == 'Fedora') | ternary('fedora','centos') }}/docker-{{ docker_edition }}.repo"
-docker_yum_repo_enable_nightly: '0'
-docker_yum_repo_enable_test: '0'
-docker_yum_gpg_key: "{{ docker_repo_url }}/{{ (ansible_distribution == 'Fedora') | ternary('fedora', 'centos') }}/gpg"
-```
-
-(Used only for RedHat/CentOS.) You can enable the Nightly or Test repo by setting the respective vars to `1`.
-
-You can change `docker_yum_gpg_key` to a different url if you are behind a firewall or provide a trustworthy mirror.
-Usually in combination with changing `docker_yum_repository` as well.
-
-```yaml
-docker_users:
-  - user1
-  - user2
-```
-
-A list of system users to be added to the `docker` group (so they can use Docker on the server).
-
-```yaml
-docker_daemon_options:
-  storage-driver: "overlay2"
-  log-opts:
-    max-size: "100m"
-```
-
-Custom `dockerd` options can be configured through this dictionary representing the json file `/etc/docker/daemon.json`.
-
-## Use with Ansible (and `docker` Python library)
-
-Many users of this role wish to also use Ansible to then _build_ Docker images and manage Docker containers on the server where Docker is installed. In this case, you can easily add in the `docker` Python library using the `geerlingguy.pip` role:
-
-```yaml
