 # Creating User Accounts
 
-The beginning to any type of user authentication is to create a user
-account. This process can take many formats, but the simplest is to
-accept user input from a form (e.g., username and password) and send it
-over to your database. For example, here\'s a snippet that shows how to
-get username and password parameters that would come when a user submits
-a form to your PHP script.
