Introducing Font Awesome 5 and SVG icons

[kkershaw]

In themes : add the SVG sprite in your theme’s /assets folder, and reference it in about.json

I was wondering how to include a custom SVG icon in my theme, in particular to replace the search, hamburger and other icons. Is this only possible if I use a remote theme with an assets folder and about.json file? I’m a bit confused how I could go about this otherwise.
