Do I still need source :gemcutter in Gemfile?

I have a file "Gemfile" in my Rails project root.

How do I use Ruby Gems?

As of 2007's release of Ruby 1.9 it is included when you download Ruby. To use RubyGems to install gems, all you have to do is type gem install [the name of the gem you want to install] . RubyGems will then go ahead and install that gem for you from its library.

Where is my gem file located?

You're correct. You don't need it any longer, and yes, it was merged.

Make sure you have an alternate source specified:
