### Additional context
I just installed on windows.
Also I just installed python and had to add it to the path and also had to "pip setuptools" to make it work.
I guess the installation instructions are not really great for windows.
Also, as you can see I am not just calling `$ manim example_scenes.py OpeningManimExample` but had to change that to make it at least run.
I am using the just cloned git repo though.
