+Build and start the simulator containers: STD_1.1.3 and OSC_2.1.0, using:
+
+./build_and_start.sh duplicate-check|ignore-duplicate
+
+Build and start the simulator container version STD_2.0.0, using two alternatives: ext-srv or kafka-srv. However, both can not be used at the same time to start A1 sim.
+
+In order to start with ext-srv:
+./build_and_start.sh duplicate-check|ignore-duplicate ext-srv|ext-srv-secure|ignore-ext-srv
+
+In order to start with kafka-srv:
+./build_and_start.sh duplicate-check|ignore-duplicate kafka-srv|kafka-srv-secure publish-resp|ignore-publish
+
+STD_2.0.0 version is now including an external server that is a Python server building RESTful API. The external server supports HTTP/HTTPS protocols.
+The description of the start parameters are explained below:
+ext-srv: Runs external server that supports HTTP protocol only.
+ext-srv-secure: Runs external server that supports HTTPS protocol as well.
+ignore-ext-srv: Ignores external server to run.
+
+STD_2.0.0 version also includes an kafka message dispatcher that is a Python server building RESTful APIs. The kafka server supports HTTP/HTTPS protocols.
+The description of the start parameters are explained below:
+kafka-srv: Runs kafka server that supports HTTP protocol only.
+kafka-srv-secure: Runs kafka server that supports HTTPS protocol as well.
+publish-resp: The flag controls the dispatcher module to decide auto responding to each requests for test purposes only.
+ignore-publish: If the A1 sim is being started using ignore flag, then the dispatcher module will look for a respone message published by south-bound module.
