+Tail mode
+-----------
+
+awsinsights allows to listen CloudWatch in live mode which is called `tail
+mode`. 
+
+It can be activated using `--tail` option. 
+
+Example - listening for ERRORs and Exceptions in tail mode:
+```
+awsinsights --timedelta 30m --appname simplebook --filter "ERROR|Exception" --tail
+```
+
+NOTE: Please notice that there might be **few mins delay** between the time when log really happened 
+and the time when it will appear in output of awsinsights' `tail mode`.
