+How to Add a Reset Password Feature
+===================================
+
+Using `MakerBundle`_ & `SymfonyCastsResetPasswordBundle`_ you can create a
+secure out of the box solution to handle forgotten passwords.
+
+First, make sure you have a security ``User`` class. Follow
+the :doc:`Security Guide </security>` if you don't have one already.
+
+Generating the Reset Password Code
+----------------------------------
+
+.. code-block:: terminal
+
+    $ php composer require symfonycasts/reset-password-bundle
+        .....
+    $ php bin/console make:reset-password
+
+The `make:reset-password` command will ask you a few questions about your app and
+generate all the files you need! After, you'll see a success message and a list
+of any other steps you need to do.
+
+You can customize the reset password bundle's behavior by updating the ``reset_password.yaml``
+file. For more information on the configuration, check out the
+`SymfonyCastsResetPasswordBundle`_  guide.
