+# Apache REEF
 
-REEF is the Retainable Evaluator Execution Framework. It makes it easier to write applications on top of resource managers (e.g. YARN). It is released under the Apache 2.0 license. To get started, there is a [Tutorial](https://github.com/Microsoft-CISL/REEF/wiki/How-to-download-and-compile-REEF). We also have a [website](http://www.reef-project.org/)
+REEF (Retainable Evaluator Execution Framework) is a scale-out computing fabric
+that makes it easier to write Big Data applications on top of resource managers
+(e.g., Apache YARN and Mesos). For example, Azure Stream Analytics is built on
+REEF and Hadoop. Apache REEF is currently undergoing incubation at the [Apache
+Software Foundation](http://www.apache.org/).
