title: Devise, allowing users to change passwords
body: <p>I have an application that has a custom registration controller, called users_controller, for devise because only Admin is able to create users.  I want to allow users to change their password by entering their old password and entering a new one and I found: <a href="https://github.com/plataformatec/devise/wiki/How-To:-Allow-users-to-edit-their-password">https://github.com/plataformatec/devise/wiki/How-To:-Allow-users-to-edit-their-password</a> but it does not give enough detail.</p>
  
  <p>What do I need to put in my routes?</p>
  
  <p>Where and what do I need to put in my views?</p>
