 # A collection of Notebooks for using IPython effectively
 
 The following notebooks showcase multiple aspects of IPython, from its basic
 use to more advanced scenarios.  They introduce you to the use of the Notebook
 and also cover aspects of IPython that are available in other clients, such as
 the cell magics for multi-language integration or our extended display
 protocol.
 
 For beginners, we recommend that you start with the 5-part series that
 introduces the system, and later read others as the topics interest you.
 
 Once you are familiar with the notebook system, we encourage you to visit our
 [gallery](https://github.com/ipython/ipython/wiki/A-gallery-of-interesting-IPython-Notebooks)
 where you will find many more examples that cover areas from basic Python
 programming to advanced topics in scientific computing.
