+you havent, do it now.
+
+PyDial uses Python 3.7 and has been previously implemented with python 2.7. Ensure
+that you use the requirements.txt file to install the appropriate dependencies
+via pip. If you do not have pip installed yet first do

+sudo apt-get install python3-pip
+
+otherwise exectued directly
+
+pip3 install -r requirements.txt
+
+To check that you have a fully functioning system, run the PyDial functional tests

+sh testPyDial
+
+You should see output similar to the following:
