IoTivity is an open source project and contributions are welcomed! Please review the Project Governance and Contribution Guidelines before submitting code or asking questions in the mailing lists. Details on how to get involved in all aspects of the IoTivity project, including account creation, can be found on https://www.iotivity.org/get-involved.
There are always a ton of things to do. Suggest we keep a wiki page with simple things that need work as a way to get started (the challenge is keeping it up to date). By no means are code contributions the only thing needed!
