# PyGame and OpenGL on Windows 10

Then I opened windows PowerShell (just a nicer term)

```py -m pip install pygame --user
py -m pip install numpy --user
py -m pip install pyopengl --user```

(I also installed NoteTab++, a nice text editor)

From there, I went to github and copied one of the examples from https://github.com/pygame/pygame/blob/master/examples/glcube.py and saved it on my desktop as myglcube.py.

In PowerShell, you just type:

```cd Desktop
py -m myglcube```

Here is my example: (here is the code)
