A good option to look page for page how your content is looking is to use JupyterLab. JupyterLab has an extension for MyST. Note that editing using JL works well for Jupyter Notebooks but not for markdown files.
Any edits made in the notebook can be directly seen when the cell (either code or markdown) is run.
Install JupyterLab with the MyST extension¶
Run JupyterLab¶
Use terminal...
Create a shortcut¶
Find the location of the file ‘\jupyter-lab.exe’ on your computer. This can be done by opening a terminal and running the command where jupyter-lab (on Windows) or which jupyter-lab (on Linux/Mac). Once you have the path, you can create a shortcut on your desktop or taskbar for easy access.
Note that when you open JL, the standard directory is not the directory of the repository, and not likely the repository you want to start from. To change this, open the properties of the startup shortcut and change the “Start in” field to the path of your repository.
