"Our book has been enable to run Python code live in the browser (thanks Max!). This extension makes code cells in your `.ipynb` book pages editable and executable by the reader! Opposed to the original sphinx-thebe extensions, our extension runs python in the reader's browser and doesn't rely on an external webserver for the python kernel. We highly recommend this extension as it allows you to use the strength of combining text/figures and code of a jupyter book with interactivity!\n",

This type of user requires only very basic knowledge in GitLab/GitHub in order to make changes to the website themselves without needing to install any software! Making adjustments using single text editor only requires the user to be able to login into GitLab/GitHub and edit .md or .ipynb files. The changes can be done directly in the main or publish branch and if a new branch is needed for the changes then the set-up and merging can be taken care of by someone more familiar in GitLab/GitHub.

- User 4 is a hybrid between type 3 and 5. Basically this user is making changes by editing the .md files locally using, for example, VS Code. Therefore, this user requires a little bit more knowledge on git (think of pulling and pushing changes) but their main focus remains to make adjustments to the content of the book by editing .md files whereas user type 4 has more knowledge to make changes to python files the book as well. This user can build the book online.
