How to install numpy for Maya

I needed to install numpy for Maya the other day because its a dependancy of a package that I use.
But how? How do you install numpy for Maya?

Like this:
1.) Press windows, type in cmd and press enter
2.) type in: cd C:\Program Files\Autodesk\Maya20??\bin
3.) type in: mayapy -m pip install numpy

Obviously, replace the ?? in your Maya install directory with your version number.
And there you go - numpy installed! :)
