No obvious way to get from Docs to GitHub

https://kotlin.github.io/kandy/ doesn't provide an easily accessible link to take a look at the GitHub project, star it, etc.

Start at https://kotlin.github.io/kandy/ and inspect how the documentation site is built and where navigation or project links are configured. Add an easily accessible link to the Kandy GitHub repository, then verify it appears on the site and reaches the project page.
