+===== Ansible Navigator =====
+Ansible Navigator uses podman to create an EE environment to run the Ansible playbooks and provides a text user interface to navigate through the documentation, inventory, and execution results.
+Install Ansible Navigator with:
+<code>
+pip3 install ansible-dev-tools ansible-navigator --user
+# or
+dnf install \
+  --enablerepo=ansible-automation-platform-2.2-for-rhel-8-x86_64-rpms \
+  ansible-navigator
+</code>
+Use it with:
+<code>
+ansible-navigator run playbook1.yaml
+ansible-navigator doc service  # Type ":{{ examples }}" to scroll to the example section of the doc
+ansible-navigator doc service -m stdout  # Getting output to stdout lets you use standard tools to search
+</code>
+===== Common Ansible Problems =====
+<code>
+ERROR: Ansible requires the locale encoding to be UTF-8; Detected ISO8859-1.
+Set the following environment variables within the shell before running ansible / ansible-playbook
+LANG="en_US.UTF-8"
+LC_CTYPE="en_US.UTF-8"
+</code>
