-Every package contains a `pyproject.toml` with the required Python packages.
-[Poetry](https://python-poetry.org/)  is used for requirement management.
-To ensure the requirements are consistent, you have to update the `poetry.lock` in addition to the `pyproject.toml` when updating/changing requirements. Additional requirements like *black* and *flake8* are provided for development. You can install them with `poetry install --with dev` inside the package-directory.

 > 📝 Do not update the requirements in the `pyproject.toml` manually. Doing so will invalidate the `poetry.lock`. Use the *poetry* application for this.
 
+#### Directory-based local libraries (no local packages)
+
+- Services do not install local libs as packages. Instead, containers set `PYTHONPATH` to include the service `src` and the needed `libs/*/src` folders.
+- During image builds, libs' third-party dependencies are installed with `poetry install --no-root` in each lib directory. The service is also installed with `--no-root`.
+- If you run services locally outside Docker, export `PYTHONPATH` accordingly, e.g. for rag-backend:
+
+  ```bash
+  export PYTHONPATH="services/rag-backend/src:libs/rag-core-api/src:libs/rag-core-lib/src:$PYTHONPATH"

 ### 1.3 Usage

 This example of the rag-template includes a WebUI for document-management, as well as for the chat.
 
-After following the setup instruction for either the [local installation](#-local-setup-instructions) or the [installation on a server](#-Deployment-to-server) the WebUI is accessible via the configured ingress.
-After uploading a file in the document-management WebUI you can start asking question about your document in the chat WebUI.
