 # libfreemkv Architecture
 
 Open source optical drive access library for 4K UHD Blu-ray, Blu-ray, and DVD.
-Rust library with no external dependencies at runtime -- profiles are bundled,
-AACS keys are derived internally, and all SCSI communication is handled in-process.
+Rust library with profiles bundled and all SCSI communication handled in-process.
+AACS decryption requires an external `keydb.cfg` (default
+`~/.config/freemkv/keydb.cfg`) — the derivation math is internal, but no AACS key
+material is compiled in; DVD CSS player keys are the only compiled-in keys.
