Amazon S3 allows you to set per-file permissions to grant read and/or write access. This is nice, but sometimes you just want to share your whole bucket with the world.

Luckily, Amazon features _bucket policies_, which allow you to define permissions for an entire bucket.
~
This example will give _read_ access to _Everyone_ on _all files_ in your bucket.

``` json
{
	"Version":"2008-10-17",
	"Statement":[{
	"Sid":"AllowPublicRead",
		"Effect":"Allow",
		"Principal": {
			"AWS": "*"
			},
		"Action":["s3:GetObject"],
		"Resource":["arn:aws:s3:::bucket/*"
		]
	}
	]
}
```

**Make sure you replace `bucket` in `arn:aws:s3:::bucket/*` with your bucket name.**

After setting this bucket policy (see 'Bucket -> Properties -> Add Bucket Policy'), all your files will be publicly readable.
