+## SVG Rendering
 
 The implementation for SVG rendering is based on the [W3C draft](https://w3c-ccg.github.io/vc-render-method/#render-svgrenderingtemplate2023).
 
-## How it works
+### How it works
 
 SVG renderering is an alternative to the existing embedded renderer method that can be achieved without creating a decentralized renderer.
 
 Instead, an SVG image needs to be provided either by directly embedded it inside an OA document, or by providing a publicly accessible link that dereferences to an SVG image. In order to correctly display data, the provided SVG should include [handlebars expressions](https://handlebarsjs.com/guide/expressions.html).
 
 At the point of display, the document to be rendered is passed to the SvgRenderer component in order for the final output to be compiled.
