AR Foundation Samples Not Working

I'm on Unity 2019.4. I imported ARFoundation via the package manager.

If I then download the AR Foundation Samples via github (https://github.com/Unity-Technologies/arfoundation-samples) and place the assets folder into my project - I get TONS of errors.

If I download the whole repo and try to open it as a 'unity project' per ReadMe instructions - Unity doesn't recognize it as a project.

Please help me understand how I can get this to work.

 

Just figured it out... for anyone else who finds this thread - here's the steps to get it to work:
1) Create a new unity project
2) Download the git repo
3) Close your unity project
4) Copy/Paste the 3 folders from the git repot (Assets, Packages, ProjectSettings) into your unity project (this will replace the existing folders that were auto-generated on creating the unity project.
5) Open unity
