All documentation for IXP Manager is linked in the support menu above. There is also a page linked there for presentations and talks which should be quiet useful.
As an open source project, the primary channel for requesting help is via our mailing list. The developers and operations staff from INEX are on this list but we also try and foster an environment where other more experienced users can help new comers.
Please subscribe here.
This list is low traffic and is also used to announce new versions, security issues, etc.
All bugs should be filed on the GitHub Issues page. It is vitally important that you file a detailed bug report with steps on how to reproduce the issue. One line / vague bug reports are likely to be closed without investigation.
The ideal feature request comes with code via a pull request. This (or commercial support) is the most probable way to get a feature into IXP Manager! Feel free to file feature requests as an issue and tag it as such.
We will give all feature requests a fair hearing and due consideration. But, those that we are unlikely to implement pro bono or those that do not align with the core purpose of IXP Manager may be closed or moved to a feature request file so as not to clog up the issue tracker.
