There are many ways to get help from the Apache Flink community. The mailing lists are the primary place where all Flink committers are present. For user support and questions use the user mailing list. Some committers are also monitoring Stack Overflow. Please remember to tag your questions with the apache-flink tag. Bugs and feature requests can either be discussed on the dev mailing list or on [Jira]({{ site.jira }}). Those interested in contributing to Flink should check out the contribution guide.

If you send us an email with a code snippet, make sure that:

1. you do not link to files in external services as such files can change, get deleted or the link might break and thus make an archived email thread useless
2. you paste text instead of screenshots of text
3. you keep formatting when pasting code in order to keep the code readable
4. there are enough import statements to avoid ambiguities
