How to install NXOpen. #1

Hello,

Thank you for making this repo. I am completely new to NX and NXOpen. I wanted to know where do you install NXOpen from? I couldn't find a pip command or something similar to install it. Does NXOpen come bundled with NX in the form of a python interpreter? If yes, is there any way to use NXOpen with a particular python interpreter as a python library?

Thank You
