-When you run the script, it will ask you do one manual signature.  It has to ask you
-to do these because it doesn't know your private key. You can edit the manual
-commands to fit your situation (e.g. if your private key is in a different
-location).
-
-NOTE: When the script asks you to run these manual commands, you need to run
-them in a separate terminal window. You need to keep the script open while you
-run them. They sign temporary test files that the script created, so if you exit
-or continue the script before you run the commands, those test files will be
-destroyed before they can be used correctly (and you'll have to run the script
-again).
-
-The `*.json` and `*.sig` files are temporary files automatically generated by
-the script and will be destroyed when the script stops. They only contain the
-protocol requests and signatures. They do NOT contain your private keys
-because this script does not have access to your private keys.
