 * If you want to encrypt plain datasets when they are received, you should use the `--encrypt` option. Datasets will then be stored encrypted at the target. Datasets that are already encrypted will still be sent over unaltered in raw-mode.
 * If you also want re-encrypt encrypted datasets with the target-side encryption you can use both options. 
 
-Note 1: The --encrypt option will rely on inheriting encryption parameters from the parent datasets on the target side. You are responsible for setting those up and loading the keys. So --encrypt is no guarantee for encryption: If you dont set it up, it cant encrypt.
 
-Note 2: Decide what you want at an early stage: If you change the --encrypt or --decrypt parameter after the inital sync you might get weird and wonderfull errors. (nothing dangerous)
