Text to update

* [Jupyter Notebook (IPython)](https://jupyter.org) -  A rich toolkit to help you make the most out of using Python interactively.

• Jupyter Notebook (IPython) - A rich toolkit to help you make the most out of using Python interactively.

Note: We should keep IPython on this line to avoid confusion. Jupyter is essentially the newest version of IPython, but IPython is probably still a more widely recognized name.

Reason for change:

Jupyter and the future of IPython

IPython is a growing project, with increasingly language-agnostic components. IPython 3.x was the last monolithic release of IPython, containing the notebook server, qtconsole, etc. As of IPython 4.0, the language-agnostic parts of the project: the notebook format, message protocol, qtconsole, notebook web application, etc. have moved to new projects under the name Jupyter. IPython itself is focused on interactive Python, part of which is providing a Python kernel for Jupyter.
