 Here are some tips on using `pybricksdev` with Jupyter notebooks.
 
-- Create a virtual environment for hosting the kernel.
-- Required packages: `pybricksdev`, `notebook`, `ipykernel`, `ipywidgets`
-- Enable widgets for progress bars: `jupyter nbextension enable --py widgetsnbextension`
+- Create a virtual environment for hosting the kernel (remember `pybricksdev` is Python 3.8 only!).
+- Use `apt`, `brew`, `pipx`, etc. and not `pip` for installing notebook server globally.
+- Required packages for kernel: `pybricksdev`, `ipykernel`, `ipywidgets`
+- Recommended packages for kernel: `matplotlib`
 - Create a named kernel: `python -m ipykernel install --user --name=pybricksdev`
-- Start a notebook server: `jupyter notebook`
+- Required packages for notebook server (classic): `notebook`, `widgetsnbextension`
+- Required packages for notebook server (new): `jupyterlab`, `jupyterlab_widgets`
+- Enable widgets for progress bars (should only be needed for older versions):
+  `jupyter nbextension enable --py widgetsnbextension`
+- Start a notebook server (classic): `jupyter notebook`
+- Start a notebook server (new): `jupyter lab`
+- Can use VS Code `ms-toolsai.jupyter` extension instead of installing and running your own server.
