 ### Config
 
 Looks like this ```Config/s3.json```:
 ```
 {
-   "accessKey": "{your-AWS-accees-key}",
-   "secretKey": "{your-AWS-secret-key}"
+"accessKey": "{your-AWS-accees-key}",
+"secretKey": "{your-AWS-secret-key}",
+"bucket": "{bucket-name}"
+}
+```
+The bucket name is an optional value so you can skip it if you want:
+```
+{
+"accessKey": "{your-AWS-accees-key}",
+"secretKey": "{your-AWS-secret-key}"
 }
 ```
