 ## Usage
 
+### Config
+
     Dalia::MiniGraphite.config({
       :graphite_host => "my.graphite.server.com",
       :graphite_port => 2003, # default 2003
       :statsd_host => "my.graphite.server.com",
       :statsd_port => 8125, # default 8125
       :mock_mode => false, # default false
       :debug_mode => true # default false
     })
 
+### Simple signals
+
     Dalia::MiniGraphite.datapoint("my.key", 120, Time.now) # to Graphite
     Dalia::MiniGraphite.counter("my.key", 120) # to StatSD
 
+### Block wrapper benchmark
 
+     result =
+       Dalia::MiniGraphite.benchmark_wrapper("key_prefix", [send_result={true,false}]) do
+         sleep(1)
+         "RESULT"
+       end
+
+     puts result # => RESULT
+
 This will send 4 signals:
 
-- key_prefix.ini            # At the begining of the block
-- key_prefix.count          # At the begining of the block, keep it for compatibility
-- key_prefix.time, ~1000    # At the end of the block, with the Benchmark.realtime result of the execution
-- key_prefix.end            # At the end of the block
+- *key_prefix.ini*            # At the begining of the block
+- *key_prefix.result*         # At the end of the block, send the block result. Only if `send_result` paramater is `true`.
+- *key_prefix.time, [ms]*     # At the end of the block, with the Benchmark.realtime result of the execution
+- *key_prefix.end*            # At the end of the block
 
-    result =
-      Dalia::MiniGraphite.benchmark_wrapper("key_prefix") do
-        sleep(1)
-        "RESULT"
-      end
+### Routes reporter for Sinatra
 
-    puts result # => RESULT
+The rack middleware must be added to the Rack chain in config.ru passing along with it a block with  config options:
 
+- *set_graphite_key "graphite_key", /route_regexp/*   #  The regular expression will be used to match the Sinatra route and the corresponding graphite_key will be used to build the Graphite metrics:
+
+"[graphite_key].count"  # The counter of the times a particular route is requested.
+"[graphite_key].duration" # The duration in milliseconds of each request/response cycle.
+
+If the requested url doesn't match any configured regular expression the Graphite metrics will not be sent.
+
+Example:
+
+    # config.ru
+
+    use Dalia::MiniGraphite::RoutesReporter do
+      set_graphite_key "app.my_app.production.routes.active_surveys", /active_surveys\/this_should_be_a_password/
+      set_graphite_key "app.my_app.production.routes.get_surveys", /\:offer_click_id\/\:panel_user_id\/\:panel_user_id_kind/
+      set_graphite_key "app.my_app.production.routes.error", /error/
+      set_graphite_key "app.my_app.production.routes.homepage", /\/$/
+    end
+
+    run MyApp::App
