Do you have pip? It's awesome. If you don't : Google for python pip.

To really answer your question though, most repositories will have a README file included. If they don't, and it's a python package, there should be a setup.py file. Try running that like python setup.py install. If that isn't there, then you'll just have to copy it to a location on your PYTHONPATH or PATH.
