 ---------
 To enable reporting of changes to the Datadog timeline, enable the report
 processor on your Puppet master, and enable reporting for your clients.
-The clients will send a run report after each check-in back to the master,
-and the master will process the reports and send them to the Datadog API.
+The clients will send a run report after each check-in back to the master.
 
+Please specify what clients/hosts you'd like to submit puppet run reports
+for by setting the puppet_run_reports option to true in the node configuration
+manifest.
 
-In your Puppet master `/etc/puppet/puppet.conf`, add these configuration options:
-
-    [main]
-    # No need to modify this section
+```ruby
+class { "datadog-agent":
+    api_key => "<your_api_key>",
+    puppet_run_reports => true
     # ...
+}
+```
 
-    [master]
-    # Enable reporting to datadog
-    reports=datadog_reports
-    # If you use other reports already, just add datadog_reports at the end
-    # reports=store,log,datadog_reports
-    # ...
+In your Puppet master `/etc/puppet/puppet.conf`, add these configuration options:
