 PDF is a page based file format, so most visible information is available via
 page-based iteration
 
 ```ruby
-    reader = PDF::Reader.new("somefile.pdf")
+reader = PDF::Reader.new("somefile.pdf")
 
-    reader.pages.each do |page|

 If you need to access the full program for rendering a page, use the walk() method
 of PDF::Reader::Page.

 For low level access to the objects in a PDF file, use the ObjectHash class like
