Installation instructions for non-developers/sys admins:
1. Extract the files to a folder. (go to the Downloads section and get the zip file)
2. Move the resulting folder to the path where your IIS sites reside
3. Go to IIS and add the folder as a site. Make sure the Application Pool is a .NET 4/Integrated Pipeline App Pool and that the bindings are properly configured.
Let me know if you get stuck in any of the steps.
