This repo has a demo app that sends an SMS message whenever the source code is updated on github.
The idea is to demonstrate a very simple connection between Jenkins and github.
If you contribute to this for the sake of a demo you should be aware that your mobile number may linger around in the source code.
If you fork this and you want it to work then you have to make sure that your shell is exporting the following variables
TWILIO_ACCOUNT: your Twilio account idTWILIO_TOKEN: your Twilio token
Enjoy,
