title: How to add user-registration form to my django app?
body: <p>I have been able to create a form where the user can input their username and password following this <a href="https://github.com/DjangoGirls/tutorial-extensions/blob/master/authentication_authorization/README.md" rel="nofollow">tutorial</a>.</p>
  
  <p>I want to be able to create a user account by: pressing a button  which will transfer the user to another page where they will fill out a form and the details are saved onto a database. I also want to make sure that no username is repeated. However, I don't know how to code it. I am very new to django hence why I am struggling. </p>
  
  <p>I am using windows and atom code editor if that makes a difference. Please can someone help me code it. </p>
