 >[!NOTE]
 >Due to the [size](https://developers.cloudflare.com/workers/platform/limits/#worker-size) of the Worker, this example can only be deployed if you're using the Workers Paid plan. Free plan users will encounter deployment errors because this Worker exceeds the 3MB size limit.
 
-## Adding Packages
-
-Vendored packages are added to your source files and need to be installed in a special manner. The Python Workers team plans to make this process automatic in the future, but for now, manual steps need to be taken.
-
-### Vendoring Packages
-
-First, install Python3.12 and pip for Python 3.12.
-
-*Currently, other versions of Python will not work - use 3.12!*
-
-Then set up your local pyodide virtual environment:
-```console
-npm run build
-```
-
-### Developing and Deploying
+## Developing and Deploying
 
 To develop your Worker run:
+
 ```console
-npm run dev
+uv run pywrangler dev
 ```
 
 To deploy your Worker run:
+
 ```console
-npm run deploy
+uv run pywrangler deploy
 ```
 
-### Testing
+## Testing
 
 To test run:
+
 ```console
-npm run test
+uv run pytest tests
 ```
 
-### Linting and Formatting
+## Linting and Formatting
 
 This project uses Ruff for linting and formatting:
 
 ```console
-npm run lint
+uv ruff format . --check
+uv ruff check .
 ```
 
-### IDE Integration
-
-To have good autocompletions in your IDE simply select .venv-pyodide/bin/python as your IDE's interpreter.
+## IDE Integration
 
-You should also install your dependencies for type hints.
-
-```console
-.venv-pyodide/bin/pip install -r requirements-dev.txt
-```
+To have good autocompletions in your IDE simply select .venv-workers/bin/python as your IDE's interpreter.
