Website with broken link

Hello there, first question here. Now I’m digging a little more in sanic.
I found a broken link here (Sanic User Guide - Running Sanic) in the link “Nginx as a proxy”.
I think the right link is to Sanic User Guide - Nginx.
Is this the best place to report something like this? Or how can I help in a better way?

And since is my first question, I like to thanks all the guys behind this framework for the work they put on this.
