+
+newrelic_plugins Cookbook
+=========================
+
+Install the newrelic_plugin_agent on your Engine Yard Cloud environment
+
+Usage
+-----
+
+1. Make sure that New Relic has been enabled for your environment
+2. Include the recipe in the `main/recipes/default.rb` recipe
+
+    ```
+    include_recipe 'newrelic_plugins'
+    ```
+
+Customization
+-----
+
+By default, the recipe will install the same plugins on every instance. If you
+need different ones on different instances, copy the newrelic_plugin_agent.yml
+file and enable the relevent ones. Then customize the recipe to write the template
+based on the instance role/name.
+
+Example:
+- Template file with 'redis' enabled on the 'redis' utility instance(s)
+- Template file with 'memcached' enabled on the 'memcached' instance(s)
+
