def description # :nodoc:
  <<-EOF
RubyGems fetches gems from the sources you have configured (stored in your
~/.gemrc).

The default source is https://rubygems.org, but you may have other sources
configured.  This guide will help you update your sources or configure
yourself to use your own gem server.

Without any arguments the sources lists your currently configured sources:

$ gem sources
*** NO CONFIGURED SOURCES, DEFAULT SOURCES LISTED BELOW ***

https://rubygems.org

This may list multiple sources or non-rubygems sources.  You probably
configured them before or have an old `~/.gemrc`.  If you have sources you
do not recognize you should remove them.

RubyGems has been configured to serve gems via the following URLs through
its history:

* http://gems.rubyforge.org (RubyGems 1.3.5 and earlier)
* http://rubygems.org       (RubyGems 1.3.6 through 1.8.30, and 2.0.0)
* https://rubygems.org      (RubyGems 2.0.1 and newer)

Since all of these sources point to the same set of gems you only need one
of them in your list.  https://rubygems.org is recommended as it brings the
protections of an SSL connection to gem downloads.

To add a private gem source use the --prepend argument to insert it before
the default source. This is usually the best place for private gem sources:

  $ gem sources --prepend https://my.private.source
  https://my.private.source added to sources

RubyGems will check to see if gems can be installed from the source given
before it is added.

To add or move a source after all other sources, use --append:

  $ gem sources --append https://rubygems.org
  https://rubygems.org moved to end of sources

To remove a source use the --remove argument:

  $ gem sources --remove https://my.private.source/
  https://my.private.source/ removed from sources
