+IPython provides a rich toolkit to help you make the most out of using Python
+interactively.  Its main components are:
+
+* A powerful interactive Python shell
+* A `Jupyter <https://jupyter.org/>`_ kernel to work with Python code in Jupyter
+notebooks and other interactive frontends.
+
+The enhanced interactive Python shells have the following main features:
+
+* Comprehensive object introspection.
+
+* Input history, persistent across sessions.
+
+* Caching of output results during a session with automatically generated
+references.
+
+* Extensible tab completion, with support by default for completion of python
+variables and keywords, filenames and function keywords.
+
+* Extensible system of 'magic' commands for controlling the environment and
+performing many tasks related either to IPython or the operating system.
+
+* A rich configuration system with easy switching between different setups
+(simpler than changing $PYTHONSTARTUP environment variables every time).
+
+* Session logging and reloading.
+
+* Extensible syntax processing for special purpose situations.
+
+* Access to the system shell with user-extensible alias system.
+
+* Easily embeddable in other Python programs and GUIs.
+
+* Integrated access to the pdb debugger and the Python profiler.
+
+The latest development version is always available from IPython's `GitHub
+site <http://github.com/ipython>`_.
