+Requirements:
+1.Python3.6.
+2.Install the template-toolkit package.
+	a. pip install Template-Toolkit-Python or 
+	b. git clone https://github.com/lmr/Template-Toolkit-Python, and set the path of the package in the codeGen.py script [as argument in sys.path.append]
+
+Inputs:
+	2 Json files:
+		generateItem.json - Defines path of templates, the class type to be generated(State/actionHandler/Enum), output directory to be produced.
+		stateMachineAppModel.json - Defines procedures, states for each procedure, event for each state, actions to be taken under each event and nextstate of the procedure.
+	
+		Existing actionHandler.h and attachActionHandlers.cpp,detachActionHandlers.cpp,s1ReleaseActionHandlers.cpp files from <top-dir>/include/mme-app/actionHandlers and <top-dir>/src/mme-app/actionHandlers respectively.
+		Place it in output directories as the output produced should be merged with existing file properly. 
+
+Output:
+	1.	mme states .cpp and header files. Copy to <top-dir>/src/mme-app/mme-states and <top-dir>/include/mme-app/mme-states
+	2.	stateFactory.h and stateFactory.cpp Copy to <top-dir>/src/mme-app/mme-states and <top-dir>/include/mme-app/mme-states
+	3.	actionHandlers
+			actionHandler.h and actionHandler source files per procedure (eg: attachActionHandlers.cpp, detachActionHandlers.cpp )
+			actionHandler.h should be placed in <top-dir>/include/mme-app/actionHandlers
+			attachActionHandler.cpp should placed in <top-dir>/src/mme-app/actionHandlers
+	4.	enums used by the MME state machine - <top-dir>/include/stateMachineFwk
+
+Execution:
+-Run the below command:
+	python codeGen.py
+
