 ## ACL
 
 For now there are some limitations:
-* [Bucket policy](https://docs.aws.amazon.com/AmazonS3/latest/userguide/bucket-policies.html) supports only one `Principal` per `Statement`.
-Principal must be `"AWS": "*"` (to refer all users) or `"CanonicalUser": "0313b1ac3a8076e155a7e797b24f0b650cccad5941ea59d7cfd51a024a8b2a06bf"` (hex encoded public key of desired user).
-* Resource in bucket policy is an array. Each item MUST contain bucket name, CAN contain object name (wildcards are not supported):
-```json
-{
-  "Statement": [
-    {
-      "Resource": [
-        "arn:aws:s3:::bucket",
-        "arn:aws:s3:::bucket/some/object"
-      ]
-    }
-  ]
-}
-```
-* AWS conditions and wildcard are not supported in [resources](https://docs.aws.amazon.com/AmazonS3/latest/userguide/s3-arn-format.html)
-* Only `CanonicalUser` (with hex encoded public key) and `All Users Group` are supported in [ACL](https://docs.aws.amazon.com/AmazonS3/latest/userguide/acl-overview.html)

 ## Locking
 
 For now there are some limitations:
+
 * Retention period can't be shortened, only extended.
 * You can't delete locks or object with unexpired lock.
