 Available options:
 build - locally builds simulator image from existing code
-start <ves-url> - starts simulator using remote docker image and connects to given VES server
-start-dev <ves-url> - starts simulator using local docker image and connects to given VES server
-stop - stops simulator
-status - prints container status
-logs - prints logs
-help - prints this message
+start - starts simulator and netopeer2 containers using remote simulator image and specified model name
+start-dev - starts simulator and netopeer2 containers using remote simulator image
+start-debug - starts only  netopeer2 container
+run-simulator - starts sending PNF registration messages with parameters specified in config.json
+stop-simulator - stop sending PNF registration messages
+stop - stops both containers
+status - prints simulator status
+clear-logs - deletes log folder
 
 Starting simulation:
-Use "./simulator.sh start". It will download required docker image from the internet and start simulator using body.json file
 
-To stop simulation use "./simulator.sh stop" command. To check simulator's status use "./simulator.sh status".
-If you want to change message parameters simply edit body.json file then run simulator again.
+- Setup environment with "./simulator.sh start". It will download required docker images from the internet and run them on docker machine
+- To start the simulation use "./simulator.sh run-simulator", which will start sending PNF registration messages with parameters specified in config.json
+
+To stop simulation use "./simulator.sh stop-simulator" command. To check simulator's status use "./simulator.sh status".
+If you want to change message parameters simply edit config.json, then start the simulation with "./simulator.sh run-simulator" again
+Logs are written to logs/pnf-simulator.log. After each "start/start-dev" old log files are moved to the archive
 
 FOR DEVELOPERS
 1. Build local simulator image using "./simulator.sh build"
-2. Run simulation with "./simulator.sh start-dev"
+2. Run containers with "./simulator.sh start-dev"
 
-If you change the source code you have to rebuild image with "./simulator.sh build" and run  "./simulator.sh start-dev" again
-
+If you change the source code you have to rebuild image with "./simulator.sh build" and run "./simulator.sh start/start-dev" again
