+Controller Isolation Tool
+Author: Phillip Shea
+Updated: 2015-May-07
+
+This tool isolates an indicated controller from the cluster. The tool takes
+a single integer argument corresponding to the number of a controller
+in a json file's ordered list of controllers. This is the controller to
+be isolated.
+
+A file named 'cluster.json' containing a list of the IP addresses and
+credentials of the controllers is required. It resides in the same
+directory as monitor.py.
+
+The file should look like this:
+
+    {
+        "cluster": {
+            "controllers": [
+                "172.17.10.93",
+                "172.17.10.94",
+                "172.17.10.95"
+            ],
+            "user": "username",
+            "pass": "password"
+        }
+    }
+
+Usage:python isolate.py [controller to be isolated]
