 Other Linux distributions may also work, at your own risk, especially if Docker runs smoothly.
 
+NOTE: AzuraCast was designed to be installed *just once* on a fresh OS.  So ``./runrole --reinstall azuracast`` is not supported in general.  However, if you accidentally damage your AzuraCast software, IIAB has posted `technical tips <./tasks/install.yml>`_ *(use at your own risk!)* in case of emergency.

+#
+# 1. But if you must, first completely uninstall Docker + WIPE AzuraCast data:
+#
+#    apt purge docker-ce docker-ce-cli containerd.io docker-compose-plugin docker-scan-plugin
+#    rm -rf /library/docker /var/lib/docker /var/lib/containerd
+#
+#    Per https://docs.docker.com/engine/install/ubuntu/#uninstall-docker-engine
+#
+# 2. REBOOT to avoid later problems with 'systemctl status docker' -- if you
+#    don't reboot, Ansible will fail below when 'docker.sh install' fails to
+#    start docker.service -- likewise if you run './docker.sh install-docker'
+#    manually in /opt/azuracast.  Either way, 'systemctl restart docker' won't
+#    work for ~2 minutes.  (Rebooting avoids all these hassles!)
+#
+# 3. Just FYI the Docker install process will rebuild its 11 core directories
+#    in /var/lib/docker -> /library/docker: (as 'docker.sh install' begins)
+#
+#    buildkit containers image network overlay2 plugins runtimes swarm tmp trust volumes
+#
+# 4. Just FYI both MySQL passwords (MYSQL_PASSWORD & MYSQL_ROOT_PASSWORD) will
+#    be WIPED from /opt/azuracast/azuracast.env (and new passwords
+#    auto-generated below, for use inside AzuraCast's Docker container).
+#
+# 5. Run './runrole --reinstall azuracast' in /opt/iiab/iiab
