+##Downloading simulator
+Official version of simulator can be downloaded for public ONAP docker registry as image.

+##Usage of simulator
+
+###Configuration
+The configuration for simulator is stored in */config/config.json* file. 
+It contains all parameters for simulation such as duration time,interval between messages and values of the configurable fields of VES message. 
+If you want to change duration or value of message sending to VES collector you just need to edit this file. 
+The message that is being sent to VES is built inside the simulator and it's content can be found in log of the simulator. 
+
+###Running simulator   
+The recommended way is to checkout PNF Simulator project from ONAP Git repository and use *simulator*.sh script
+If you copy *simulator.sh* script to another location, keep in mind to copy also *docker-compose.yml* and directories: *config,json_schema and netconf*.
+In order to run simulator, invoke ./simulator.sh start
+Script downloads if necessary needed Docker images and runs instances of these images.
+
+###Logging
+It is possible to get access to logs by invocation of *./simulator.sh* logs. 
+The content of the logs is related to the last simulator run. 
+Every start of simulator will generate new logs.
