-The handler must be given and should be a normal Ruby file that sets up the
-environment and calls `Ernicorn.expose` for any server modules. See the
-[examples/handler.rb][h] file for more info.
+The ernicorn server attempts to load the config file given or
+`config/ernicorn.rb` when no config file is specified. See the example config
+file [examples/config.rb][c] to get started. All [Unicorn config options][r] are
+supported.
+
+The config file should require any libraries needed for the server and register
+server modules with `Ernicorn.expose(:modulename, TheModule)`. See the
+[examples/handler.rb][h] file for a simple example handler.
