Simply install the templating package from pypi and execute the templating tool. Unless the config flag is specified (-c, --config) templating searches for a config file named templating.yaml in the current directory, if it is not found ~/.templating.yaml might be used, if it exists.

pip install templating
templating -c myconf.yaml
