For dummies installation tutorial for starting

[PetiPandaRou]

The installation part (http://sphinx-tutorial.readthedocs.org/start/) should be more "for the dummies" oriented:

• What are prerequisites for the installation ?
• On which OS is it possible to install it ?
• How do I create my first Sphinx documentation page ?

Also, it could be great to be more proactive on users' possible errors. For example, for pip install sphinx, you can explain that it's possible to have an permission error. I had it and rerun the command with sudo.

Also what is the command to run the python server permanently ? This could be usefull.
