+[^1]: Except for paks compressed using frozen index which has significant
+    complexity and only existed for UE 4.25 anyway.
+[^2]: Zlib, Gzip, and Zstd are supported. Not all compression algorithms are
+    available in all games.
 
 Supports reading encrypted (both index and/or data) and compressed paks.
 Writing does not support compression or encryption yet.
