 ## Changes
 
 The files are not changed. Each folder holds the same bytes as the original
 checkpoint, and `manifest.json` lists the files of the checkpoint. The layout
-`<name>/<date>/` is the same as in the cache of `surya`.
+`<task>/<source>-<date>/` names the task, the source of the model, and the
+date of the checkpoint.
