I noticed on a recent video from Miguel that he was accessing MonoDoc with the contents of http://iosapi.xamarin.com
Is there an install location for MonoDoc (there doesn't seem to be one at http://www.mono-project.com/Documentation that works) that allows us to add http://iosapi.xamarin.com/ to MonoDoc?
Pressing help in MonoDevelop does not seem to open anything.
I have submitted a bug fix request to Xamarin and will update this when it is completed.
As per this SO answer, I had to run /Applications/MonoDevelop.app/Contents/MacOS/MonoDoc.app/Contents/MacOS/macdoc
in Terminal in order for the Help menu item to start working in MonoDevelop.
MonoTouch installs the documentation for MonoDoc to use. You do not need to do anything, except hit Help from MonoDevelop
