+One further change you might want to make to the file above is the cross-origin API access block. This is what's used on
+my own Spothole server to make sure that other third-party web-based software can get the data from my instance. If you want
+*your* Spothole instance to be set up the same way, so that others can write software in JavaScript that can access it,
+leave this intact. But if you want your Spothole instance to only be usable by scripts running on the web server you write,
+you can remove this block. (Note that this doesn't stop other people writing *non-web-based* software that accesses your
+Spothole API—the enforcement of cross-origin headers only happens within the user's browser. If you need to lock your
+instance down so that no-one else can access it with *any* software, that's an aspect of nginx config that you will need
+to find help with elsewhere.)
