+# io.js Build Raspberry Pi Setup
+
+For setting up Raspberry Pi boxes
+
+```text
+Host iojs-ns-pi1-1
+  HostName xx.xx.xx.xx
+  User pi
+...
+```
+
+Note that these hostnames are also used in the *ansible-inventory* file. The IP addresses will need to be updated each time the servers are reprovisioned.
+
+To set up a host, run:
+
+```text
+$ ansible-playbook -i ../ansible-inventory ansible-playbook.yaml
+```
+
+Start-up of the Jenkins slaves is manual (for now), run:
+
+```text
+$ ssh iojs@iojs-ns-pi1-1 ./start.sh
+```
+
+**Users**: The ansible-vars.yaml file contains a list of users who's GitHub public keys are pulled and placed into authorized_keys for both root and iojs users. This file should be updates when new users are added to the build project who are able to help maintain the containerized builds.
