These are the docs for the HTML theme.
The HTML theme allows you to easily host HTML files. You can essentially use Small Victories as a hosting service!
The following article is about hosting HTML/CSS/JS (and media assets) with Small Victories. For information on building custom themes using HTML/Liquid, head over to the Developer resources.
When you create a new site using the HTML Theme, you’ll see it in your Small Victories folder with a few files in it. These files will give you an example of how you can host HTML pages and linked files.
