https://cwiki.apache.org/confluence/display/NIFI/Contributor+Guide is a
good place to start.
You can search through open PRs here https://github.com/apache/nifi/pulls
If you see PRs of interest there we'd love help getting them reviewed and
actually tested. That is the long pole in many cases. There is often some
old/outdated just needing to be closed PRs but there are ones that just need
some time/love to get to the finish line.
You can also look in JIRA for open items as sometimes, though rarely, there
are patches submitted the old-fashioned way via JIRA.
Thanks!
