Now we can quickly add a way to register users. This is already built in FOS; we just need to use it. To do so, we need to (as with login) enable routing, add a template, and link to the registration form. Add the following rule to routing:

fos_user_registration:
  resource: "@FOSUserBundle/Resources/config/routing/registration.xml"
  prefix: /register

Update the security file with a new access control entry at the start as follows:

access_control:
    - { path: ^/register, role: IS_AUTHENTICATED_ANONYMOUSLY }

This modification will add the required routings. Now we need to override the template for registration. To do this, add two files. One file is app/Resources/FOSUserBundle/views/Registration/register.html.twig with the following content:

{% extends "::base.html.twig" %}

{% trans_default_domain 'FOSUserBundle' %}

{% block body %}
<div class="ui one column stackable page grid" style="margin-top: 150px;">
    <div class="column twelve wide">
        <form...
