Thanks for the article! I recently spent some time going through the process of learning VirtualEnv / Pip; after looking at several tutorials, agreed that this is one of the better ones out there. A few other things I saw in other articles that you might like to clarify (though I understand there's a tradeoff with simplicity/clarity).

(1) specifically state that `pip freeze` is how to create requirements file (as folks have said in comments already) (2) add "further reading" link on VirtualEnvWrapper, as it adds some convenience methods to ease use of VirtualEnv (3) the "yolk" package shows you what's currently installed; it can be helpful to `pip install yolk` then run `yolk -l` to view the different packages installed in each of your envs. (4) when installing a package, you can specify the version, e.g. `pip install mod==1.1`, whereas `pip install mod` will simply install the latest
