+# Editing Code In Pry
+
+[Pry](http://pryrepl.org/) provides an enhanced REPL experience for Ruby.
+One of the enhancements it provides is the ability to open your preferred
+editor within a pry session. This makes it easy to compose and edit
+multi-line blocks of code.
+
+Try it out by typing `edit` within a pry session. Once you are ready, you
+can save the file which will prompt pry to interpret the contents of your
+file within the context of the pry session.
