# Installing using setup.py

To make pyglet available to all users, or to avoid having to set the `PYTHONPATH` for each session, you can install it into your Python's `site-packages` directory.

From a command prompt on Windows, change into the extracted pyglet source archive directory and type:

    python setup.py install

On Mac OS X and Linux you will need to do the above as a priveleged user; for example using `sudo`:

    sudo python setup.py install

Once installed you should be able to `import pyglet` from any terminal without setting the `PYTHONPATH`.
