I've downloaded a theme via Keentheme and want to use it in my project.
The getting started tutorial (<a href="https://www.youtube.com/watch?v=ApO_obOK_00" rel="nofollow noreferrer">https://www.youtube.com/watch?v=ApO_obOK_00</a>) at around 14:20 instructs me to change all html files to php files and to use 
This doesn't work.</p>

<p>The html files contain numerous instructions like the following:

./partials/_mobile-header-base.html</p>

<p>The tutorial only walks through the php include method - can anyone help?</p>
