 Add this line to your application's Gemfile:
 
-	gem 'mongoid_traffic'
+```Ruby
+gem 'mongoid_traffic'
+```
 
 And then execute:
 
-	$ bundle
+```
+$ bundle
+```
 
 Or install it yourself as:
 
-	$ gem install mongoid_traffic
+```
+$ gem install mongoid_traffic
+```
 
 ## Usage
 
 Log your traffic like this:
 
-	Mongoid::TrafficLogger.log
+```Ruby
+Mongoid::TrafficLogger.log
+```
 
 Or, in case of Rails, you can use the `.after_action` macro with the `#log_traffic` helper method in your controllers:
 
-	class MyController < ApplicationController
-		after_action :log_traffic, only: [:show]
-	end
+```Ruby
+class MyController < ApplicationController
+	after_action :log_traffic, only: [:show]
+end
+```
 
 ### Scope
 
 You can scope the log using the (optional) `scope:` argument:
 
-	Mongoid::TrafficLogger.log(scope: '/pages/123')
+```Ruby
+Mongoid::TrafficLogger.log(scope: '/pages/123')
+```
 
 Or, in case of Rails controller:
 
-	class MyController < ApplicationController
-		after_action :log_scoped_traffic, only: [:show]
-	end
+```Ruby
+class MyController < ApplicationController
+	after_action :log_scoped_traffic, only: [:show]
+end
+```
 
 By default, the `:log_scoped_traffic` method scopes your log by the request path (for example '/pages/123'). You can override this behavior with custom scope like this:
 
-	class MyController < ApplicationController
-		after_action :log_scoped_traffic, only: [:show]
+```Ruby
+class MyController < ApplicationController
+	after_action :log_scoped_traffic, only: [:show]
 
-		private
-		
-		def log_scoped_traffic
-			super.log_scoped_traffic(scope: 'my-scope-comes-here')
-		end
+	private
+
+	def log_scoped_traffic
+		super.log_scoped_traffic(scope: 'my-scope-comes-here')
 	end
+end
+```
 
 It might be good idea to use both methods in order to log access to the whole site as well as access to individual pages:
 
-	class MyController < ApplicationController
-		after_action :log_traffic, only: [:show]
-		after_action :log_scoped_traffic, only: [:show]
-	end
+```Ruby
+class MyController < ApplicationController
+	after_action :log_traffic, only: [:show]
+	after_action :log_scoped_traffic, only: [:show]
+end
+```
 
 ## Accessing the log
 
 ### Access count
 
 The total number of views within a specific month can be accessed like this:
 
-	Mongoid::TrafficLog.for_year(2014).for_month(8).access_count
+```Ruby
+Mongoid::TrafficLog.for_year(2014).for_month(8).access_count
+```
 
 The total number of views per scope per specific date like this:
 
-	Mongoid::TrafficLog.for_date(Date.today).access_count
+```Ruby
+Mongoid::TrafficLog.for_date(Date.today).access_count
+```
 
 ### User Agent
 
 Optionally, you can pass 'User-Agent' header string to the logger:
 
-	Mongoid::TrafficLogger.log(user_agent: user_agent_string)
+```Ruby
+Mongoid::TrafficLogger.log(user_agent: user_agent_string)
+```
 
 ### Referer
 
 Optionally, you can pass 'User-Agent' header string to the logger:
 
-	Mongoid::TrafficLogger.log(referer: http_referer_string)
+```Ruby
+Mongoid::TrafficLogger.log(referer: http_referer_string)
+```
