The default path of the configuration file is config/config.yaml.
A sample configuration file can be found in the same directory: config/sample.config.yaml.
All configuration files in this directory (config) will be ignored by Git. To change the default configuration file path set the environment variable OQAPI_CONFIG to the desired path.
To create a new configuration file simply copy the sample configuration file and change the values.
cd config/
cp sample.config.yaml config.yaml
