GitHub functionality issue?

Is there, or should there be, live functionality for the lab “Analyzing bank customers with pandas,” linked below?
My fork (nor the master) allow for any edits. I am able to work on the project via Jupyter in my browser, is this the expected method? Perhaps I need something additional in GitHub?

Thank you for your time.

hey, to work on a GitHub project with Jupyter Notebooks you can clone or download the project from GitHub and run the Jupyter Notebooks locally, or run the project directly on Google Colab by entering the GitHub URL of the project there.
