+# Example
+
+This is an example using the AWS SDK for Go to upload object with progress.
+We use CustomReader to implement it
+
+
+# Usage
+
+The example uses the bucket name provided, one key for object, and output the progress to stdout.
+The Object size should larger than 5M or your will not see the progress
+
+```sh
+AWS_REGION=<region> go run putObjWithProcess.go <credential> <bucket> <key for object> <local file name>
+```
