+Description
+===========
+
+Installs bluepill RubyGem and configures it to manage services. Also includes a LWRP.
+
+Requirements
+============
+
+Bluepill is a pure Ruby service management tool/library, so this cookbook should work on any system. The attributes do set up paths based on FHS locations, see below.
+
+Attributes
+==========
+
+Default locations for bluepill are in "FHS compliant" locations.
+
+* `node["bluepill"]["bin"]` - Path to bluepill program, default is 'bluepill' in the RubyGems binary directory.
+* `node["bluepill"]["logfile"]` - Location of the bluepill log file, default "/var/log/bluepill.log".
+* `node["bluepill"]["conf_dir"]` - Location of service config files (pills), default "/etc/bluepill".
+* `node["bluepill"]["pid_dir"]` - Location of pidfiles, default "/var/run/bluepill"
+* `node["bluepill"]["state_dir"]` - Location of state directory, default "/var/lib/bluepill"
+* `node["bluepill"]["init_dir"]` - Location of init script directory, default selected by platform.
+
+Resources/Providers
+===================
+
+This cookbook contains an LWRP, `bluepill_service`. This can be used with the normal Chef service resource, by using the `provider` parameter, or by specifying the `bluepill_service` shortcut. These two resources are equivalent.
+
+    service "my_app" do
+      provider bluepill_service
+      action [:enable, :load, :start]
+    end
+
+    bluepill_service "my_app" do
+      action [:enable, :load, :start]
+    end
+
+The load action should probably always be specified, to ensure that if bluepill isn't running already it gets started. The 
+
+The recipe using the service must contain a template resource for the pill and it must be named `my_app.pill.erb`, where `my_app` is the service name passed to the bluepill service resource. 
+
+Usage
+=====
+
+Be sure to include the bluepill recipe in the run list to ensure that the gem and bluepill-related directories are created. This will also make the cookbook available on the system and other cookbooks won't need to explicitly depend on it in the metadata.
+
+If the default directory locations in the attributes/default.rb aren't what you want, change them by setting them either in the attributes file itself, or create attributes in a role applied to any systems that will use bluepill.
+
+Example pill template resource and .erb file:
+
+    template "/etc/bluepill/my_app" do
+      source "my_app.pill.erb"
+    end
+
+    Bluepill.application("my_app") do |app|
+      app.process("my_app") do |process|
+        process.pid_file = "/var/run/my_app.pid"
+        process.start_command = "/usr/bin/my_app"
+      end
+    end
+
+See bluepill's documentation for more information on creating pill templates.
