The open source ONOS community was launched at the end of 2014 and has grown rapidly since then. This tutorial will provide information about the community and will provide step by step information about how to get involved and contribute to the project. There are a number of exciting contribution opportunities to learn about and areas where you can help drive the evolution of the project. The focus will be on code contributions, although we will touch on other contribution opportunities including documentation, QA, and more.
