Thank you, Marios. I've added a "Put it together" section which describes the folder strucvture required to include the SVG image in the README content.
As for implementation, please review my example file, "hello-world.svg" to see how you can incorporate "foreignObject" in your SVG file. It will not be a full HTML file but include a root object compatible to XHTML specifications, where I used a "div". This object may include a style element as well as other HTML/XHTML tags
