 SNS's encryption is mainly useful when the store is being _transferred over a
 network_.
 
+## Vim Encryption
+As of SNS v2b, SNS will look for a file named .vim in its store. If found, SNS will start in Vim mode, calling Vim directly instead of the environment's $EDITOR, and using Vim's native functionality for in-place encryption.
+
+At this time, SNS does not provide a way to convert between store formats. Additionally, SNS v2b does not support printing Vim-encrypted notes to stdout; you will need to open the note for editing and copy/paste out of Vim for the time being.
+
+Finally, when using Vim mode, treat -c and -e separately.

 ## Tips and Tricks
 * To list all notes in all notebooks, use `sns -l .`
