Calling Unity API Reference from MonoDevelop

I tried to call a Unity API Reference from MonoDevelop, but it does not working. Can you help me, please?

Maybe changed type of links to Documentation or something else?

Change language to English on the main page. It works for me.

Ok, format link has changed, but now I have a new question. How I can using that new format link in my MonoDevelop, anybody knows?
