+# RocketMQ Externals
+
+There are some RocketMQ external projects, with the purpose of growing the RocketMQ community.
+
+## RocketMQ-Console-Ng
+A console for RocketMQ
+
+## RocketMQ-JMS
+RocketMQ-JMS is an implement of JMS specification,taking Apache RocketMQ as broker. Now we are on the way of supporting JMS 1.1 and JMS2.0 is our final target.
+
+## RocketMQ-Flume-Ng
+
+This project is used to receive and send messages between
+[RocketMQ](http://rocketmq.incubator.apache.org/) and [Flume-ng](https://github.com/apache/flume)
+
+1. Firstly, please get familiar with [RocketMQ](http://rocketmq.incubator.apache.org/) and [Flume-ng](https://github.com/apache/flume).
+2. Ensure that the jar related to [RocketMQ](http://rocketmq.incubator.apache.org/dowloading/releases) exists in local maven repository.
+3. Execute the following command in rocketmq-flume root directory
+
+ `mvn clean install dependency:copy-dependencies`
+
+4. Copy the jar depended by rocketmq-flume to `$FLUME_HOME/lib`(the specific jar will be given later)
+
+
+## RocketMQ-Spark
+
+Apache Spark-Streaming integration with RocketMQ. Both push & pull consumer mode are provided.
+For more details please refer to rocketmq-spark README.md.
+
+## RocketMQ-Docker
+Apache RocketMQ Docker provides Dockerfile and bash scripts for building and running docker image.
