Run a notebook at home
  1. Install uv.
  2. Click the download icon beside any notebook above.
  3. Open a terminal in the folder where you saved it and run:
uvx --refresh --python 3.14 --with symbolica marimo edit quick-start.py

Replace quick-start.py with your downloaded filename. uv installs Python, Symbolica, and marimo for you. The notebook opens in your browser and runs on your computer. If marimo asks to install a missing package, click Install.
