+      # This method outputs without escaping a string. Since escaping tags is
+      # now default, this can be used when you don't want Rails to automatically
+      # escape tags. This is not recommended if the data is coming from the user's
+      # input.
+      #
+      # For example:
+      #
+      # <%=raw @user.name %>
