     Additionally, the timestamp metadata (timestamp.json) should also be written
     to disk whenever it is updated. It is optional for an implementation to
-    write identical copies at timestamp.digest.json for record-keeping purposes,
+    write identical copies at digest.timestamp.json for record-keeping purposes,
     because a cryptographic hash of the timestamp metadata is usually not
     known in advance. The same step applies to the root metadata (root.json),

+    although an implementation must write both root.json and digest.root.json
     because it is possible to download root metadata both with and without
     known hashes. These steps are required because these are the only metadata
     files that may be requested without known hashes.
