 This project uses [openapi-python-client](https://github.com/openapi-generators/openapi-python-client) to generate an API client from the IDL. To update the generated client:
 
 ```bash
-poetry run openapi-python-client update --path iwf-idl/iwf-sdk.yaml --config .openapi-python-client-config.yaml
+cd iwf && poetry run openapi-python-client update --path ../iwf-idl/iwf-sdk.yaml --config .openapi-python-client-config.yam
 ```
-Then update the version in `iwf-api/pyproject.toml` so that poetry can know that the local path dependency package is updated.
 
-Then run `poetry update` to update the local path dependency.
