I want to be able to output the current loop iteration to my template.

According to [the docs](https://jinja.palletsprojects.com/en/3.0.x/templates/), there is a `loop.counter` variable that I am trying to use:

```
<ul>
{% for user in userlist %}
  <li>
      {{ user }} {{loop.counter}}
  </li>
      {% if loop.counter == 1 %}
          This is the First user
      {% endif %}
{% endfor %}
</ul>

```

But is being outputed to my template. What is the correct syntax?
