 # Configuration
 
 ## Flask
-The default Flask application uses a [LocalConfig](https://github.com/lyft/amundsenfrontendlibrary/blob/master/amundsen_application/config.py) that looks for the metadata and search services running on localhost. In order to use different end point, you need to create a custom config class suitable for your use case. Once the config class has been created, it can be referenced via the [environment variable](https://github.com/lyft/amundsenfrontendlibrary/blob/master/amundsen_application/wsgi.py#L5): `FRONTEND_SVC_CONFIG_MODULE_CLASS`

 ## React Application
 ### Application Config
-Certain features of the React application import variables from an [AppConfig](https://github.com/lyft/amundsenfrontendlibrary/blob/master/amundsen_application/static/js/config/config.ts#L5) object. The configuration can be customized by modifying [config-custom.ts](https://github.com/lyft/amundsenfrontendlibrary/blob/master/amundsen_application/static/js/config/config-custom.ts).
