Please explain what this sentence means (copied from http://docs.rubygems.org/read/chapter/3)

"Make sure you add the GEM_HOME setup to your profile, so that RubyGems can find the location of your gem repository."

I am on Windows 7. What is "GEM_HOME setup" and how do I add it to my profile?

Thank you.

   GEM_HOME is an environment variable that tells RubyGems where to find or install gems from.

   You can see the default value of GEM_HOME by doing gem env in a command prompt and see the value of it around GEM PATHS (first element listed there)

   You can learn about setting environment variables using GUI or command line:

   Please note that setting that environment variable is not required unless you installed Ruby using Administrative privileges and normally you don't have them.

   Hope this helps.
