When exporting SVG files with tools like Sketch, you might see something like the following:

<!-- Generator: Sketch 44.1 (41455) - http://www.bohemiancoding.com/sketch -->
<title>Page 1</title>
<desc>Created with Sketch.</desc>

However, the autogenerated title and desc are terrible for accessibility because screen readers rely on the metadata for voice over.

As a result, always make it a habit to update these elements:

<title>Icon</title>
<desc>A description of the icon.</desc>
