Welcome to IPython. Our full documentation is available on our website; if you downloaded a built source distribution the docs/source directory contains the plaintext version of these manuals. If you have Sphinx installed, you can build them by typing cd docs; make html for local browsing.
See the install page to install IPython.
The Notebook, Qt console and a number of other pieces are now parts of Jupyter. See the Jupyter installation docs if you want to use these.
Officially, IPython requires Python version 2.7, or 3.3 and above. IPython 1.x is the last IPython version to support Python 2.6 and 3.2.
You can run IPython from this directory without even installing it system-wide by typing at the terminal:
$ python -m IPython
