== Project Governance

Like all Apache projects, Cassandra is independently managed by its Project Management Committee (PMC). The Cassandra PMC is tasked with project management—especially technical direction, votes on new committers and PMC members for the project, and sets policies as well as formally voting on software product releases. Our guiding philosophies are to default to the dev list and “decide as a community,” and to favor PMC minimalism.

While contributors do not have a specific governance role, they are crucial to the project’s success. Read the docs to learn how to xref:/development/index.adoc[contribute to Cassandra,window=blank], and review our https://cwiki.apache.org/confluence/display/CASSANDRA/Cassandra+Project+Governance[governance,window=blank] page to understand how we vote on code contributions.

=== Reporting Bugs

----------

[openblock, float75 full-800]
----------
If you encounter a problem with Cassandra, the first places to ask for help are the xref:community.adoc#discussions[user mailing list,window=blank] and the #cassandra https://s.apache.org/slack-invite[Slack channel,window=blank].

If, after having asked for help, you suspect that you have found a bug in Cassandra, you should report it by opening a ticket through the https://issues.apache.org/jira/browse/CASSANDRA[Apache Cassandra JIRA tracking system,window=blank]. Please provide as much detail as you can on your problem. Don’t forget to indicate which version of Cassandra you are running and on which environment.

To create a JIRA account, please request it on xref:community.adoc#discussions[the #cassandra or #cassandra-dev channels on ASF Slack], or on xref:community.adoc#discussions[the user or dev mailing list].
