docs/data/reusables/codespaces/jupyterlab-in-default-image.md

The default container image includes JupyterLab, so codespaces created from the default image will always have JupyterLab installed. For more information about the default image, see "Introduction to dev containers" and the devcontainers/images repository. If you're not using the default image in your dev container configuration, you can install JupyterLab by adding the ghcr.io/devcontainers/features/python feature to your devcontainer.json file. You should include the option "installJupyterlab": true. For more information, see the README for the python feature, in the devcontainers/features repository.
