# Signals used by django-registration

Much of `django-registration`‘s customizability comes through the ability to write and use different workflows for user registration. However, there are many cases where only a small bit of additional logic needs to be injected into the registration process, and writing a custom workflow to support this represents an unnecessary amount of work. A more lightweight customization option is provided through two custom signals which the built-in registration workflows send, and custom workflows are encouraged to send, at specific points during the registration process; functions listening for these signals can then add whatever logic is needed.

For general documentation on signals and the Django dispatcher, consult Django’s signals documentation. This documentation assumes that you are familiar with how signals work and the process of writing and connecting functions which will listen for signals.
