manheim-c7n-tools and :ref:`related commands <index.main_components>` expect to be executed with a current working directory of a "configuration repository", matching the layout described in :ref:`policies.repo_layout`. An example configuration repository can be seen at https://github.com/manheim/manheim-c7n-tools/tree/master/example_config_repo. An example of a repository utilizing the policygen ability to layer multiple sets of policies can be seen at https://github.com/manheim/manheim-c7n-tools/tree/master/example_config_multi_repo.
By default, manheim-c7n-tools and related commands (such as policygen) use a configuration file at ./manheim-c7n-tools.yml. The schema of this configuration file is documented in the :py:const:`~manheim_c7n_tools.config.MANHEIM_CONFIG_SCHEMA` constant in the source code. In addition, a commented example is available in the GitHub repo.
