Tellervo is open source software so we openly welcome developers who would like to contribute. The code is hosted at Github. The Github webpage includes details of how to access the code anonymously (read only) but if you'd like to contribute please get contact us with your Github account details.
The standard manual contains a large section devoted to describing how developers can build and contribute to Tellervo, including step-by-step instructions explaining how to set up an integrated development environment.
Webservice schema documentation
In addition to the documentation within the manual, if you are attempting to write a client that can read data from a Tellervo server, you may find the online schema documentation useful.
Bugs and feature requests
The development of Tellervo is managed through the Github bug tracking system. You can browse this system to see if a bug or feature that you are interested in is already being handled. If not, please contact us or use the Github ticketing system to submit a new ticket.
