Trying to import packages on Pycharm

[KTam0916]

I'm trying to learn to code in Python (via Pycharm) and use the Kalman Filter in it. In this book there is this line - "import kf_book.gh_internal as gh". I don't have any idea how to import this package as it is not an available package in Pycharm. What do I do? I can see the package is hosted on github here...
