How to set AWS Bucket Policy to Public?

{
	"Version": "2012-10-17",
	"Statement": [
		{
			"Sid": "PublicReadGetObject",
			"Effect": "Allow",
			"Principal": "*",
			"Action": [
				"s3:GetObject"
			],
			"Resource": [
				"arn:aws:s3:::BUCKET_NAME/*"
			]
		}
	]
}

Note that you need to modify the ARN's BUCKET_NAME to the name of your bucket.
