 ## Quick Start with Single Binary ##
 * Download the latest binary from https://github.com/seaweedfs/seaweedfs/releases and unzip a single binary file `weed` or `weed.exe`. Or run `go install github.com/seaweedfs/seaweedfs/weed@latest`.
+* `export AWS_ACCESS_KEY_ID=admin ; export AWS_SECRET_ACCESS_KEY=key` as the admin credentials to access the object store.
 * 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 running `weed volume -dir="/some/data/dir2" -mserver="<master_host>:9333" -port=8081` locally, or on a different machine, or on thousands of machines. That is it!
