 ### How to run the example
 
-These examples all include configuring and starting influxdb (a time series database) and grafana (a metrics dashboard).
+This example includes configuring and starting influxdb (a time series database) and grafana (a metrics dashboard).
 
-The following scripts can be used to start the demos
+The example:
+  - Starts containers for Influxdb and Grafana (using Dockwer)
+  - Starts snapd
+  - Gets, loads and starts snap plugins
+  - Creates and starts a task that collects from psutil and publishes to InfluxDB
+
+Start the example by running `run-psutil.sh`
 
-- run-pcm.sh *\<docker-machine name\>* 
-  - starts snapd
-  - creates and starts a task that collects from both the pcm and psutil plugins
-- run-psutil.sh *\<docker-machine\>*
-  - starts snapd
-  - creates and starts a task that collects from psutil plugin
-- ./run.sh *\<docker-machine\>*   
-  - configured influxdb and grafana only

 ### Requirements
-- docker-machine 
-    + installed and configured
-
-- docker-compose
-    + installed
+- docker
+- docker-compose 
+- netcat
