	 * * depth - Directory depth at which the installation was found.
	 * * alias - WP-CLI alias, if one is registered.
	 *
	 * These fields are optionally available:
	 *
	 * * wp_path - Path that can be passed to `--path=<path>` global parameter.
	 * * db_host - Host name for the database.
	 * * db_user - User name for the database.
	 * * db_name - Database name for the database.
	 *
	 * ## OPTIONS
	 *
	 * <path>
	 * : Path to search the subdirectories of.
	 *
	 * [--skip-ignored-paths]
	 * : Skip the paths that are ignored by default.
	 *
	 * [--include_ignored_paths=<paths>]
	 * : Include additional ignored paths as CSV (e.g. '/sys-backup/,/temp/').
	 *
	 * [--max_depth=<max-depth>]
	 * : Only recurse to a specified depth, inclusive.
	 *
	 * [--fields=<fields>]
	 * : Limit the output to specific row fields.
	 *
	 * [--field=<field>]
	 * : Output a specific field for each row.
	 *
	 * [--format=<format>]
	 * : Render output in a specific format.
	 * ---
	 * default: table
	 * options:
	 *   - table
