How to use Jupyter notebook

I wonder how I can access to Jupyter notebook?? I didnt find any tips on this from the course

The programming assignments are behind a paywall in these courses. The way to get to the assignments is by clicking the “Work in Browser” links on the Programming Assignment pages in each Week. But that will only work if you are paying the subscription fee or have Financial Aid or are using the course through a paid program through a university or your company.

If what you are saying is that you can open the Jupyter notebooks, but don’t know how to use them, that was covered and introduced in DLS Course 1.

If I am simply missing your point, please give us more details about what you are asking.
