Once you clone this repo perform the following steps:

bundle install
bin/rails db:setup
bin/rails s

You should now have the application running at http://localhost:3000

This is a user registration form. Here are some important files to keep in mind:

• app/models/user.rb is the user model. validations and callbacks go here.
• app/controllers/users_controller.rb is the user controller. action filters go here.
• app/views/users/new.html.erb is the view template of the form. the errors need to be displayed here.
• config/routes.rb shows you which resources and routes are available.

Go to http://localhost:3000/users/new
