 ### default
-The default recipe installs [Prometheus][] using the default `install_method` and
-supervises the [Prometheus][] binary under [runit][].
+The `default` recipe installs creates all the default [Prometheus][] directories,
+config files and and users.  Default also calls the configured `install_method`
+recipe and finally calls the prometheus `service` recipe.
+
+### source
+The `source` recipe builds Prometheus from a Github source tag.
+
+### binary
+The `binary` recipe retrieves and installs a pre-compiled Prometheus build from
+a user-defined location.
+
+### service
+The `service` recipe configures Prometheus to run under a process supervisor.
+Default supervisors are chosen based on distribution. Currently supported
+supervisors are init, runit, systemd and bluepill.  (Upstart coming soon)
+
+Resource/Provider
+-----------------
+
+### prometheus_job
+
+This resource adds a job definition to the Prometheus config file.  Here is an
+example of using this resource to define the default Prometheus job:
+
+```ruby
+prometheus_job ‘prometheus’ do
+  scrape_interval   ‘15s’
+  target            “http://localhost#{node[‘prometheus’][‘flags’][‘web.listen-address’]}#{node[‘prometheus’][‘flags’][‘web.telemetry-path’]}”
+end
+```
+
+Note: This cookbook uses the accumulator pattern so you can define multiple
+prometheus_job’s and they will all be added to the Prometheus config.
+
+Externally managing `prometheus.conf`
+-------------------------------------
+
+If you prefer to manage your `prometheus.conf` file externally using your own
+inventory or service discovery mechanism you can set
+`default[‘prometheus’][‘allow_external_config’]` to `true`.
