If you are interested in contributing a NetBeans module, we recommend the following steps.
Check whether someone else has already written a plugin that does what you want:
Assuming that no one else has anything solid, start coding!
NetBeans Plugin Quick Start
and other tutorials on platform.netbeans.org to learn how.
If you need web hosting space, a project page, or a file versioning system,
we recommend you request a project on java.net or Kenai.com!
Remember to put some license notice or at least a copyright on the files that you publish.
Log on as a NetBeans community member and
submit your plugin to the NetBeans plugin portal
to make it available to other NetBeans users.
