The tutorial is a single Python Notebook, tutorial.ipynb. It uses helper functions from the toolkit. The best way to learn is to do: please follow the below instructions on getting started so you can change, run and experiment with the code in the notebook as you read.

This tutorial assumes you have basic knowledge of Python. In addition, this tutorial uses the following tools:

• ollama to run the models locally on your computer

First, let's make sure everything is installed correctly. Open your terminal and check the versions:

uv --version
ollama --version

Next, start ollama by running the following command:
