Add new icon to footer?

[Brian S. Yandell]

Hi,
I have successfully forked your jekyll-now repository and started to build my own pages (https://byandell.github.io). Thank you!

What I wanted to do is add another icon on the footer of the default layout. To my understanding, that might involve additions to the following files:

• _config.yml # add line under footer-links:
• _include/svg-icons.html # add line for new icon
• _sass/svf-icons.scss # add line with icon SVG details (including image)

The image I want to use is from UW-Madison https://brand.wisc.edu/resource/crest-only-logo-for-web-digital-use-full-color/ (see https://github.com/byandell/byandell.github.io/blob/master/images/README.md and https://github.com/byandell/byandell.github.io/blob/master/images/uw-crest-color-web-digital.svg). UW naturally does not want alteration of their logos, but it seems that jekyll is already doing some SVG image imbedding.

Is there a "simple", "straight-forward" way to use an icon not already in Jekyll?
Thanks for any insights.
Brian
