Following @martinRenou's suggestion, I've been reading the doc Deploying JupyterLite with xeus-python on Github Pages, which recommends using https://github.com/jupyterlite/xeus-python-demo as a template.
Now, I have a beginner's question (I'm not familiar with the way Github Pages actions are configured): how easy it is to transition from a repo created from the "official" demo (https://github.com/jupyterlite/demo) to a xeus-python deployment? Is it just about modifying a few files? Is this even possible?
In case such a transition is possible, I think it may be interesting to paste this information at https://xeus-python-kernel.readthedocs.io/en/latest/deploy.html#on-github-pages.
