+## 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.

+### Compared to MinIO ###
+
+MinIO follows AWS S3 closely and is ideal for testing for S3 API. It has good UI, policies, versionings, etc. SeaweedFS is trying to catch up here. It is also possible to put MinIO as a gateway in front of SeaweedFS later.
+
+MinIO metadata are in simple files. Each file write will incur extra writes to corresponding meta file.
+
+MinIO does not have optimization for lots of small files. The files are simply stored as is to local disks.
+Plus the extra meta file and shards for erasure coding, it only amplifies the LOSF problem.
+
+MinIO has multiple disk IO to read one file. SeaweedFS has O(1) disk reads, even for erasure coded files.
+
+MinIO has full-time erasure coding. SeaweedFS uses replication on hot data for faster speed and optionally applies erasure coding on warm data.
+
+MinIO does not have POSIX-like API support.
+
+MinIO has specific requirements on storage layout. It is not flexible to adjust capacity. In SeaweedFS, just start one volume server pointing to the master. That's all.
+
 ## 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.
+* More tools and documentation, on how to manage and scale the system. For example, how to move volumes, automatically balancing data, how to grow volumes, how to check system status, etc.

+* 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)!
