-A tool for testing xmpp servers load
+
+A tool for connecting virtual devices to the Rolling Stock platform. 
+Devices need to be registered and credentials prepared in a JSON file 
+put in input.json (or specified in a variablle) 
+
+Sample input.json file structure: 
+
+```

+{"username": "DEVICE197", "host": "rolling-stock-sandbox2-openfire.onsmartengineering.com", "port": 5222, "ping": 15, "password": "a32c695ccde9"},
+{"username": "DEVICE198", "host": "rolling-stock-sandbox2-openfire.onsmartengineering.com", "port": 5222, "ping": 15, "password": "c93f60d35d51"},

+{"username": "DEVICE200", "host": "rolling-stock-sandbox2-openfire.onsmartengineering.com", "port": 5222, "ping": 15, "password": "07fd03b6fce0"}
+]
+```
+
+The tool sends regular presence messages (with harcoded dummy versions content)
+and properly responds with "unsupported command" to any command sent to it. 
+
+
+## Usage: 
+
+```./rolling-stock-display-simulation-tool```
+
+## Building
+
+If the target system is linux amd-64 based you can just copy the binary and use it. 
+Otherwise build the binary like every other golang binary and then copy it. 
+
+```go build```
+
