Make call to action button on landing page lead to "Documentation" instead of "View on GitHub"

[olafurpg]

I have seen a lot of Microsite websites with an action button on the landing page that points to "View on GitHub". For example https://pureconfig.github.io/

I think it would be nice if the call to action button pointed to "Documentation" instead. Feel free to close this issue, just wanted to report this since I have several times browsed a repo on GitHub, opened the website link, accidentally clicked on "View on GitHub" to bring me back to the GitHub repo.
