Markdown fields

In a Markdown type field, you can enter text in Markdown syntax and ACF will automatically render it as HTML in the metafield. 

Both your original Markdown and the rendered HTML are available via .html and .markdown properties like this:

<h3>{{ product.metafields.accentuate.my_markdown_title.html }}</h3>
<p>The title was rendered from this Markdown: "{{ product.metafields.accentuate.my_markdown_title.markdown }}"</p>
