How do I install the Ruby ri documentation?

Question

I\'ve recently installed Ruby 1.9.1 on Windows 7, and apparently it doesn\'t come with the standard ri documentation. So when I do \'ri Array\', I get:

C:\\

Seems you have installer Ruby 1.9.1 distributed by the RubyInstaller project.

You can use the Windows Help Files (CHM) that came with the installer instead of the ri documentation.

The problem of the RI documentation is that some versions of RDoc have problems generating it and also generated more than 10 thousands files which slowed down the installers considerably.
