Master Branch:
Storm is a distributed realtime computation system. Similar to how Hadoop provides a set of general primitives for doing batch processing, Storm provides a set of general primitives for doing realtime computation. Storm is simple, can be used with any programming language, is used by many companies, and is a lot of fun to use!
The Rationale page explains what Storm is and why it was built. This presentation is also a good introduction to the project.
Storm has a website at storm.apache.org. Follow @stormprocessor on Twitter for updates on the project.
Documentation
Documentation and tutorials can be found on the Storm website.
Developers and contributors should also take a look at our Developer documentation.

Issue tracker
In case you want to raise a bug/feature or propose an idea, please use Apache Jira
Which list should I send/subscribe to?
If you are using a pre-built binary distribution of Storm, then chances are you should send questions, comments, storm-related announcements, etc. to user@storm.apache.org.
If you are building storm from source, developing new features, or otherwise hacking storm source code, then dev@storm.apache.org is more appropriate.
If you are committers and/or PMCs, or contributors looking for following up and participating development of Storm, then you would want to also subscribe issues@storm.apache.org in addition to dev@storm.apache.org.
What will happen with storm-user@googlegroups.com?
All existing messages will remain archived there, and can be accessed/searched here.
New messages sent to storm-user@googlegroups.com will either be rejected/bounced or replied to with a message to direct the email to the appropriate Apache-hosted group.
IRC
You can also come to the #storm-user room on freenode. You can usually find a Storm developer there to help you out.
