To create a component, first create a components directory in the root of your views directory. Each component should have a directory with the component name, and a template.twig file. Here's how you'd create a simple <Button /> component

views/
    components/
        Button/
            template.twig

template.twig

<a class="btn" :href="href">
    <Children />
</a>

To use it, place it in one of your views:

<div class="content">
    <h2>Contact Us for a Quote</h2>
    <Button href="/contact">Contact Us</Button>
</div>
