+## Self-posting stream
+
+The script post_avg.py reads the average load from the file "/proc/loadavg" and sends the value to the specified
+stream at the engine url. the script is called using:
+
+    python post_avg.py <stream_id> <interval_in_seconds> <engine_base_address>
+
+Example use
+
+    python post_avg.py asd21 30 http://localhost:8000
+
+the above example will post '{"value": <load_avg>}' every 30 seconds to http://localhost:8000/streams/asd21/data
+
+The script posts using curl and thus requires curl to be installed.
