If you want to stay as up to date as possible with NewtonVR, the best plan is to clone the repo from Github and take changes often. We'll show you the easy way to do that here.
Depending on the git client you install, cloning may be different. We're going to assume you downloaded the Github desktop client. Go to the repo website with the link above and click the green "Clone or download" button. Then click "Open in desktop".
Open a command line on Windows by hitting the Windows key and typing in "cmd", then right click on "Command Prompt" and click "Run as Administrator".
mklink /D c:\svn\MyProject\Assets\NewtonVR c:\git\NewtonVR\Assets\NewtonVR
Replace the path to your existing project and the path to the github repo in the command above. The first parameter is the location you want to put NewtonVR and the second parameter is the location the NewtonVR folder in the Assets directory of your local NewtonVR repo.
You should now be able to open your existing project and see the NewtonVR folder in the root of your assets directory. Open the example scene in NewtonVR/Example/NVRExampleScene and you should be good to go!
