 Append the following to your Chef client configs, usually at `/etc/chef/client.rb`
 
 ```ruby
-    require "chef-metrics"
+  require "chef-metrics"
 
-    metric_handler = ChefMetrics.new do
-      # see examples below
-    end
+  metric_handler = ChefMetrics.new do
+    # see examples below
+  end
 
-    report_handlers << metric_handler
-    exception_handlers << metric_handler
+  report_handlers << metric_handler
+  exception_handlers << metric_handler
 ```
 
 Alternatively, you can use the Chef cookbook
 [LWRP](http://community.opscode.com/cookbooks/chef_handler).
 
 ```ruby
-    chef_gem "chef-metrics"
+  chef_gem "chef-metrics"
 
-    handler_path = File.join(node["chef_handler"]["handler_path"], "chef_metrics.rb")
+  handler_path = File.join(node["chef_handler"]["handler_path"], "chef_metrics.rb")
 
-    directory File.dirname(handler_path) do
-      recursive true
-    end
+  directory File.dirname(handler_path) do
+    recursive true
+  end
 
-    file handler_path do
-      content "require 'chef-metrics'"
-    end
+  file handler_path do
+    content "require 'chef-metrics'"
+  end
 
-    action_block = Proc.new do
-      # see examples below
-    end
+  action_block = Proc.new do
+    # see examples below
+  end
 
-    chef_handler "ChefMetrics" do
-      source handler_path
-      arguments action_block
-    end
+  chef_handler "ChefMetrics" do
+    source handler_path
+    arguments action_block
+  end
 ```
 
 ## Examples
 
 The following examples are "action" blocks:
 
 ```ruby
-    metric_handler = ChefMetrics.new do
-      # action block
-    end
+  metric_handler = ChefMetrics.new do
+    # action block
+  end
 ```
 
 Note: I recommend adding logging, timeouts, and error handling to the following.
 
 ### Graphite
 
 ```ruby
-    require 'socket'
+  require 'socket'
 
-    socket = TCPSocket.new(GRAPHITE_HOST, GRAPHITE_PORT)
-    socket.write(graphite_formatted)
-    socket.close
+  socket = TCPSocket.new(GRAPHITE_HOST, GRAPHITE_PORT)
+  socket.write(graphite_formatted)
+  socket.close
 ```
 
 ### Sensu
 
 ```ruby
-    require 'socket'
-
-    sensu_result = {
-      :name => "chef_report",
-      :type => "metric",
-      :handler => "metrics",
-      :output => graphite_formatted
-    }
-
-    socket = TCPSocket.open('127.0.0.1', 3030)
-    socket.write(sensu_result.to_json)
-    socket.close
+  require 'socket'
+
+  sensu_result = {
+    :name => "chef_report",
+    :type => "metric",
+    :handler => "metrics",
+    :output => graphite_formatted
+  }
+
+  socket = TCPSocket.open('127.0.0.1', 3030)
+  socket.write(sensu_result.to_json)
+  socket.close
 ```
