instructions.md

• create the file above in the paths with '_' replaced with '/'
• edit /etc/statsd/statsd_conf.js to suit your environment
• install golang, clone dockrun and build it
• edit /etc/init/statsd.conf to point dockrun from where it was built in the previous step
• run start statsd and afterwards docker ps which should show the statsd deamon running, and using port '8125/udp' on the host.
