+## Quick Start ##
+* Download the latest binary from https://github.com/chrislusf/seaweedfs/releases and unzip a single binary file `weed` or `weed.exe`
+* Run `weed server -dir=/some/data/dir -s3` to start one master, one volume server, one filer, and one S3 gateway.
+
+Also, to increase capacity, just add more volume servers by `weed volume -dir="/some/data/dir2" -mserver="<master_host>:9333" -port=8081` locally or a different machine. That is it!

 By default, the master node runs on port 9333, and the volume nodes run on port 8080.
 Let's start one master node, and two volume nodes on port 8080 and 8081. Ideally, they should be started from different machines. We'll use localhost as an example.

 ## Dev Plan ##
 
-More tools and documentation, on how to maintain and scale the system. For example, how to move volumes, automatically balancing data, how to grow volumes, how to check system status, etc.
-Other key features include: Erasure Encoding, JWT security.

+* Integrate with Kubernetes. build [SeaweedFS Operator](https://github.com/seaweedfs/seaweedfs-operator).
+* Add ftp server.
+* Read and write stream data.
+* Support structured data.
 
 This is a super exciting project! And we need helpers and [support](https://www.patreon.com/seaweedfs)!
 
-BTW, We suggest run the code style check script `util/gostd` before you push your branch to remote, it will make SeaweedFS easy to review, maintain and develop:
