In the point 7 it is stated the following:

7. Use Tailwind classes in your templates:

{% load tailwind_tags %}
<link href="{% tailwind_css %}" rel="stylesheet">

<h1 class="text-4xl font-bold text-blue-600">Hello Tailwind!</h1>

However it should be as follows:

7. Use Tailwind classes in your templates:

{% load tailwind_tags %}
{% tailwind_css %}

<h1 class="text-4xl font-bold text-blue-600">Hello Tailwind!</h1>

It's just a minor detail :)
