Django Troubleshooting

https://www.djangoproject.com/download/

I am installing Django for Python on Win XP and came across this problem during installation:
 

tar xzvf Django-1.4.2.tar.gz  cd Django-1.4.2  sudo python setup.py install


What does "cd" mean? DOes it mean that I have to use command line to type it?
