+# Contributing to lumberjack

+It is more important to us that you are able to contribute.
+
+That said, some basic guidelines, which you are free to ignore :)

+# Contributing Documentation and Code Changes
+
+If you have a bugfix or new feature that you would like to contribute to
+logstash, and you think it will take more than a few minutes to produce the fix
+(ie; write code), it is worth discussing the change with the logstash users and
+developers first! You can reach us via
+[jira](https://github.com/jordansissel/lumberjack), the [mailing
+list](http://groups.google.com/group/logstash-users), or via IRC (#logstash on
+freenode irc)
