+# Apache Kafka #
+
+See our [web site](http://kafka.apache.org) for details on the project.
+
+## Building it ##
+1. ./sbt update
+2. ./sbt package
+3. ./sbt assembly-package-dependency
+
+To build for a particular version of Scala (either 2.8.0, 2.8.2, 2.9.1, 2.9.2 or 2.10.1), change step 2 above to: 
+2. ./sbt "++2.8.0 package"
+
+To build for all supported versions of Scala, change step 2 above to: 
+2. ./sbt +package
+
+## Running it ##
+Follow instuctions in http://kafka.apache.org/documentation.html#quickstart
+
+## Running unit tests ##
+  ./sbt test
+
+## Building a binary release zip or gzipped tar ball ##
+  ./sbt release-zip
+  ./sbt release-tar 
+The release file can be found inside ./target/RELEASE/.
+
+## Other Build Tips ##
+Here are some useful sbt commands, to be executed at the sbt command prompt (./sbt). Prefixing with "++<version> " runs the
+command for a specific Scala version, prefixing with "+" will perform the action for all versions of Scala, and no prefix
+runs the command for the default (2.8.0) version of Scala. -
+
+tasks : Lists all the sbt commands and their descriptions
+clean : Deletes all generated files (the target directory).
+compile : Compile all the sub projects, but not create the jars
+test : Run all unit tests in all sub projects
+release-zip : Create all the jars, run unit tests and create a deployable release zip
+release-tar : Create all the jars, run unit tests and create a deployable release gzipped tar tall
+package: Creates jars for src, test, docs etc
+projects : List all the sub projects 
+project sub_project_name : Switch to a particular sub-project. For example, to switch to the core kafka code, use "project core-kafka"
+
+The following commands can be run only on a particular sub project -
+test-only package.test.TestName : Runs only the specified test in the current sub project
+run : Provides options to run any of the classes that have a main method. For example, you can switch to project java-examples, and run the examples there by executing "project java-examples" followed by "run" 
+
+For more details please see the [SBT documentation](https://github.com/harrah/xsbt/wiki)

+## Contribution ##
+
+Kafka is a new project, and we are interested in building the community; we would welcome any thoughts or [patches](https://issues.apache.org/jira/browse/KAFKA). You can reach us [on the Apache mailing lists](http://kafka.apache.org/contact.html).
+
+To contribute follow the instructions here:
+ * http://kafka.apache.org/contributing.html
+
+We also welcome patches for the website and documentation which can be found here:
+ * https://svn.apache.org/repos/asf/kafka/site
