+Podman has builtin defaults for command line options. These defaults can be overridden using the containers.conf configuration files.
+
+Users can modify defaults by creating the `$HOME/.config/containers/containers.conf` file. Podman merges its builtin defaults with the specified fields from this file, if it exists. Fields specified in the users file override the built-in defaults.
+
+Podman uses builtin defaults if no containers.conf file is found.
