Junebug is built on the Foundation's of another Praekelt.org project, Vumi. In 2010, the Praekelt Foundation built TxtAlert, a mobile service that sends automated, personalized SMS reminders to patients on chronic medication. Responding to the needs of the project, we saw the potential to build a mobile messaging platform that could serve both NGOs and commercial clients. The result is Vumi.
Vumi for developers
The Vumi code is hosted at the public GitHub repository at github.com/praekelt/vumi. If you want to contribute we encourage you to clone the repository and issue a pull-request so we can review the changes. Also, have a read through our recommended document as familiarity will aid in getting your contributions accepted as quickly as possible. We maintain a set of Debian packages on our Praekelt Foundation Launchpad.
