- Learn how to install, run, and use ONOS, as per the Administrator Guide
- Learn how to set up the development/test environment and the usage of JIRA and Gerrit, and testing and coding guidelines as per the Developer Guide
- Reference relevant parts of the Architecture and Internals Guide, Javadocs, and Developer's Guide Appendices
For step 2. of the above, readers interested in development should refer to Contributing to the ONOS Codebase, and readers interested in the documentation effort should focus on Contributing to ONOS Documentation.
An account is required to access the various contributor services and access rights, such as JIRA issue creation. An account may be created at http://onosproject.org/register/.
The ONOS Project is a composite of the ONOS SDN platform itself and the various projects using it (applications and use cases). Information about the ongoing projects may be found on [Projects]. Many of these projects will have an Epic associated with them so that the tasks associated with them may easily be found.
Proposing a new project or task
Anyone can approach the mailing lists with project ideas and proposals. For example, if a developer has written a new application or a provider for a new protocol, and wishes to contribute it back to ONOS, it is a good idea for them to drop a line on the mailing list for feedback and further suggestions, rather than to submit a pull request without a warning.
If you are working on a task, and are stuck, don't be afraid to ask questions - it's certainly in everyone's interest to move the project forward! However, please be sure to search existing documentations and mailing list archives before doing so, or the response you get may consist of a link to a page or something similarly terse. Likewise, If you have log files, or steps for recreating an odd behavior, attach or mention those to your question as well - Just saying "It's broken" without the specifics will just result in a response asking for those materials.
If you encounter unexpected or incorrect behavior, first make sure that you understand what the correct behavior should be (and why it should be that way), and confirm that you are using the system correctly based on the documentation. Try to isolate the issue as much as possible, by finding the minimum set of steps (or a small, simple piece of code) that can reliably reproduce the problem. Make sure to include a transcript or log of any input steps or output. Finally, to submit the bug report itself, follow the instructions at Using Jira to create an issue: bugs, feature requests, documentation.
