Did you know you can specify a Github repo or custom path to a gem in your Gemfile? Either stay up to date with bleeding edge changes or fork your own version. In your Gemfile:
# Referencing Github gem 'sg-ruby', :git => 'git://github.com/simplegeo/simplegeo-ruby.git' # Referencing local copy gem 'sg-ruby', :path => "/Users/user/gems/simplegeo-ruby"
You can use HTML tags for formatting. Wrap code in <code> tags and multiple lines of code in <pre><code> tags.
