 This shouldn't be used for high-traffic websites.  Instead, you should serve
 your static files from something like Apache, nginx, or a CDN.
+
+Note:
+
+If you are creating a @cabal@ package that needs to work with @cabal-install@,
+the @\"dir\"@ you want to serve needs to be a relative path inside your
+project root, and all contained files need to be listed in your
+@.cabal@-file under the @extra-source-files@ field so that they are
+included and available at compile-time.
