2021 JupyterBook (JB) guide
Problems: Inline equations with $ something $ is confused when I put "- amsmath in" _config.yml. So I do not use "- amsmath".
Install anaconda3 using Anaconda3-2021.05-Linux-x86_64.sh.
Install JB using pip install -U jupyter-book. Execute jupyter-book create mynewbook to create a template. Compile using jupyter-book build mynewbook.
Copy (i.e., git push) all the content in mynewbook/_build/html/ to my github. To enable hosting, on github do this: Settings > GitHub Pages > Source > Select branch > main.
