 To use an existing checkpoint, just ensure the `docker run` includes a mount such as:
 `type=bind,src=PATH/TO/CHECKPOINTS,dst=/transfer-checkpoint`. Upon running, the checkpoints will be automatically used as starting point.
 
+Checkpoints don't typically use automatic mixed precision nor fully-connected layer normalization and mostly use a standard number of hidden layers (2048 unless specified otherwise). So don't change those parameters to fine-tune from them.
