-### The goal
+## The goal
 My goal is to create to smallest docker container for my web static files. The advantage of Go is that you can generate a fully static binary, so that you don't need anything else.
 
 ### Wait, I've been using old versions of GoStatic and things have changed!
 
 Yeah, decided to drop support of unsecured HTTPS. Two-years ago, when I started GoStatic, there was no automatic HTTPS available. Nowadays, thanks to Let's Encrypt, it's really easy to do so. If you need HTTPS, I recommend [caddy](https://caddyserver.com).

-### Why?
+## Why?
 Because the official Golang image is wayyyy too big (around 1/2Gb as you can see below) and could be insecure.

 The fallback option is principally useful for single-page applications (SPAs) where the browser may request a file, but where part of the path is in fact an internal route in the application, not a file on disk. goStatic supports two possible usages of this option:
