Running this Project requires a Android device with API 14 or above

I'm new to Xamarin and just downloaded Xamarin 5.5.2 and installed in my Windows system. Went thru the instructions to get "Hello World" to run and all I get is either "Does not support minimum target SDK" error if I run the AndroidForms.Android or "Running this Project requires a Android device with API 14 or above" if I run from the solution. I can't create virtual emulator because there are no images to support the API I'm using.
Yu would think that everything to run the sample would be included with the download.
Can anyone explain in layman's terms what I need to do to get this supposedly simple sample to run.
