Broken links on documentation home

[rosalynnas]

The links on the documentation home page are not working. For example, the "Quick start" link is:

• https://docs.sublayer.com/docs/quick/_start.md

But the working sidebar link is:

• https://docs.sublayer.com/docs/quick_start/

Every link apart from "View on GitHub" returns a 404

Thanks so much for catching and reporting this! We just moved over to a new docs site and looks like we missed updating the link format on these.

Just deployed a fix!
