-Run a python script to generate the test data sets
+The next step is to generate the test data, which could be done in two ways.
+
+First option is to run a python script to generate the test data sets
 
 `python3 /vagrant/test/streaming-sim/StreamingSim.py`
 
-Test the generated data set by executing the following command
+This script could also be used to clear the generated data by using the '-c' option
+
+`python3 /vagrant/test/streaming-sim/StreamingSim.py -c`
+
+The second option is to directly run the testing module, which will detect if the data was generated, and if not, will automatically
+generate the data before executing the tests. Keep in mind that if the test data is being generated using this way, a 10 seconds timeout 
+is given after the generation is finished so that the data could properly be inserted into the database. If the data was already generated 
+using the first option, only the tests would be executed.
+
+The command for running the testing module is
 
 `pytest -s /vagrant/test/streaming-sim/VerifySimResults.py`
