 ## Jupyter Notebook Deprecation Notice
 
 Following [Jupyter Notebook notice](https://github.com/jupyter/notebook#notice), we encourage users to transition to JupyterLab.

+This can be done by passing the environment variable `JUPYTER_ENABLE_LAB=yes` at container startup,
 more information is available in the [documentation](https://jupyter-docker-stacks.readthedocs.io/en/latest/using/common.html#docker-options).
 
 At some point, JupyterLab will become the default for all of the Jupyter Docker stack images, however a new environment variable will be introduced to switch back to Jupyter Notebook if needed.

+Conda is configured by default to use only the [`conda-forge`](https://anaconda.org/conda-forge) channel.
 However, alternative channels can be used either one shot by overwriting the default channel in the installation command or by configuring `conda` to use different channels.
 The examples below show how to use the [anaconda default channels](https://repo.anaconda.com/pkgs/main) instead of `conda-forge` to install packages.

 This means that it does not check dependencies. This choice is a tradeoff to cover the main requirements while achieving reasonable test duration.
 However it could be easily changed (or completed) to cover also dependencies `package_helper.installed_packages()` instead of `package_helper.specified_packages()`.
