+## Using the `pipx-package` Helper
+
+The `pipx-package` helper is a convenient way to install Python packages via pipx. It simplifies the installation process and ensures that the packages are installed in isolated environments.
+
+To use the `pipx-package` helper, follow these steps:
+
+1. **Add the Helper to Your Feature**: In your `devcontainer-feature.json` file, add the `pipx-package` helper to the `installsAfter` array. For example:
+
+    ```json
+    "installsAfter": [
+        "ghcr.io/devcontainers-extra/features/pipx-package",
+        "ghcr.io/devcontainers/features/python"
+    ]
+    ```
+
+2. **Modify the Install Script**: In your `install.sh` script, use the `pipx-package` helper to install the desired Python package. For example:
+
+    ```bash
+    $nanolayer_location \
+        install \
+        devcontainer-feature \
+        "ghcr.io/devcontainers-extra/features/pipx-package:1.1.9" \
+        --option package='your-package' --option version="$VERSION"
+    ```
+
+3. **Test the Installation**: Ensure that the package is installed correctly by running the appropriate tests.
