# This is called a "heredoc" or "here document". It is used to create a multi-line string, and you use it by starting with << and an all caps word, in this case END. Ruby then reads everything into a string until it sees another END. You can use any word, not just END, so if your string has the word "END" in it, you would use something different like <<BIGDOC and end with BIGDOC. The last thing is the string includes all the indentation.
