 # Telegraf
 
-*This chart has been deprecated as of version 0.2.1 and will not be updated. Please use the telegraf-s and telegraf-ds charts instead.*

 The command removes all the Kubernetes components associated with the chart and deletes the release.

 ## Configuration
 
-The default configuration parameters are listed in `values.yaml`. To change the defaults, specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,
+The default configuration parameters are listed in `values.yaml`.
 
 ```console
-$ helm install --name my-release \

+$ helm install --name telegraf stable/telegraf
 ```
 
-The above command prevents the single telegraf instance from deploying.

-Alternatively, a YAML file that specifies the values for the above parameters can be provided while installing the chart. For example,
-
-```console
-$ helm install --name my-release -f values.yaml stable/telegraf
+Outputs and inputs are configured as arrays of key/value dictionaries. Additional examples and defaults can be found in [values.yaml](values.yaml)
+Example:
+```
+outputs:
+  - influxdb:
+      urls: []
+        # - "http://influxdb.monitoring:8086"

-## Telegraf Configuration
-
-This chart deploys the following by default:
-
-- `telegraf` (`telegraf-ds`) running in a daemonset with the following plugins enabled
-  * [`cpu`](https://github.com/influxdata/telegraf/tree/master/plugins/inputs/system)
-  * [`disk`](https://github.com/influxdata/telegraf/tree/master/plugins/inputs/system)
-  * [`docker`](https://github.com/influxdata/telegraf/tree/master/plugins/inputs/docker)
-  * [`diskio`](https://github.com/influxdata/telegraf/tree/master/plugins/inputs/system)
-  * [`kernel`](https://github.com/influxdata/telegraf/tree/master/plugins/inputs/system)

-  * [`system`](https://github.com/influxdata/telegraf/tree/master/plugins/inputs/system)
-
-- A single `telegraf` deployment (`telegraf-s`) with an associated service running the following plugins:
-  * [`prometheus`](https://github.com/influxdata/telegraf/tree/master/plugins/inputs/prometheus)
-  * [`influxdb`](https://github.com/influxdata/telegraf/tree/master/plugins/inputs/influxdb)
-  * [`statsd`](https://github.com/influxdata/telegraf/tree/master/plugins/inputs/statsd)

-### Supported Outputs
-
-The following telegraf output plugins are supported for both the daemonset and the single instance. To enable them uncomment them in `.Values.{{ "daemonset" | "single" }}.outputs`:
-
-- [`amqp`](https://github.com/influxdata/telegraf/tree/master/plugins/outputs/amqp)
-- [`influxdb`](https://github.com/influxdata/telegraf/tree/master/plugins/outputs/influxdb)

-
-### Service Plugins - Single Instance
-
-The single telegraf also supports all service plugins. To enable them uncomment the named plugin in `.Values.single.inputs` section. The associated service exposes the ports if it is enabled:
-
-- [`tcp_listener`](https://github.com/influxdata/telegraf/tree/master/plugins/inputs/tcp_listener)
