+You can name the file anything, but it must end in .prf.

 The last command means it will ignore any file with a name ending in `.flac`.

 ## Automatic Runs
 
 The first command means this will run but also confirm which files will be deleted, and which will be transferred, us `batch = true` instead.
+Or you can deleted that line in the `.prf` file and run it with a flag:

+> unison -batch *backup*.prf
 
 Set unison to run with crontab or a systemd unit file to have directories synchronize automatically.
 
 
 ## Problem Solving
 
-Unison is extremely sensitive to version changes.
-Both machines must have exactly the same version of unison installed, as well as the same version of `ocaml`.

-Check with:
-
-> unison -version
-
 You will see data files summarizing what has happened in the `~/.unison` directory.
 If something goes wrong, you may be prompted to delete these to start again.
