+## Repair Parameters
+
+`repair.npy` is a required QuickTalk runtime parameter file. It is not a standalone neural network checkpoint. The runtime loads it after the main QuickTalk model to apply fixed repair parameters during post-processing, helping map the model output back to the template face more consistently.
+
+Keep `repair.npy` in the same QuickTalk model directory as `quicktalk.pth`.

 ## Usage With OmniRT
 
 Set the model root and start the QuickTalk runtime through OmniRT:
