Usually, such information is included in the documentation of the gem. It can 
be either in the API documentation which rubygems automatically creates when 
you install the gem or on the gem website. In the case of pdf-writer, the 
project's home page, which you can access from rubyforge, includes a manual 
(http://ruby-pdf.rubyforge.org/pdf-writer/manual/manual.pdf). At the beginning 
of chapter 2, there's a simple example, which begins with the line

require 'pdf/writer'

I hope this helps
