 ## Registering
 
-    $app->register(new Flintstones\Rest\ServiceProvider(), array(
-        'rest.fos.class_path'           => __DIR__.'/vendor',
-        'rest.serializer.class_path'    => __DIR__.'/vendor',
-    ));
+    $app->register(new Flintstones\Rest\ServiceProvider());
+
+## Overriding parameters
+
+The following can be overridden:
+
+* `'rest.priorities'`
+  This is an array of formats your code is capable of
+  sending back a response as. A negotiation takes place
+  to determine which is most suitable based on the
+  request's Accept header.
+* `'rest.fallback'`
+  This is the format to fall back on if no suitable
+  format could be negotiated. This can be set to NULL
+  if you would like a 406 HTTP status error to be
+  returned instead.
+* `'rest.decoders'`
+  This is an array that refers to decoder services
+  which are used to decode request body content.
+  Default decoders are included for JSON and XML,
+  but you can override this if necessary.
+
+Any of these you wish to override must be overridden
+prior to the service completing its setup, i.e. before
+its `register()` method has executed. Therefore they must
+either be set on `$app` prior to registering the service,
+or they must be given in an array to it's constructor
+(*not* the second optional parameter of `$app->register()`
+unlike most Silex service providers).
+
+Example #1:
+
+    $app->register(new Flintstones\Rest\ServiceProvider(array(
+        'rest.priorities' => array('html', 'json', 'xml'),
+        'rest.fallback' => null,
+    )));
+
+Example #2:
+
+    $app['rest.priorities'] = array('html', 'json', 'xml');
+    $app['rest.fallback'] = null;
+
+    $app->register(new Flintstones\Rest\ServiceProvider());
+
+Example #3:
+
+    $app['rest.decoders.custom'] = function ($app) {
+        //code...
+    };
+
+    $app->register(new Flintstones\Rest\ServiceProvider(array(
+        'rest.decoders' => array(
+            'json' => 'rest.decoders.json',
+            'xml' => 'rest.decoders.xml',
+            'custom' => 'rest.decoders.custom',
+        ),
+    )));
+
+Note that if you wish to replace `$app['rest.decoder.json']`
+and/or `$app['rest.decoder.xml']`, do so after registering.
