This is a very basic problem. I must have missed something obvious. This is one of those things where I don't even know what to search for.
I created a basic go "Hello World" app. It works great. What I want to do is now is to make changes to that web page.
I cloned the source code to a local repo, then changed the hello world text in the go file, and then I pushed that change up. My change is visible in the "master" branch.
But what do I do now? How do I get this change to be live on the web site? This is where I am lost.
