Application templates Now that you've seen how generators can be used _inside_ an application, did you know they can also be used to _generate_ applications too?

Then we pose a question to the user about whether or not they would like to install Devise. If the user replies "y" or "yes" to this question, then the template will add Devise to the +Gemfile+ outside of any group and then runs the +devise:install+ generator. This template then takes the users input and runs the +devise+ generator, with the user's answer from the last question being passed to this generator. @@ -403,7 +403,7 @@ Whilst the final section of this guide doesn't cover how to generate the most aw h3.
