 ## Required Global Variable Manipulation
-libmutton provides a `global.GetPassphrase` global variable that all clients must set. This approach allows for different types of clients (CLI, GUI, TUI) to prompt for the passphrase in the most appropriate way.
+- `global.GetPassphrase` must be set to allow for different types of clients (CLI, GUI, TUI) to prompt for the passphrase in the most appropriate way.
+- `crypt.Daemonize`, true by default, determines whether to make use of the RCW daemon for passphrase caching. This may be best to disable for interactive clients.
 
 ## Required Arguments
 - `clipclear`: Should be accepted by all non-interactive CLI libmutton implementations (not required for interactive GUI/TUI implementations). In order to clear the clipboard on a timer, non-interactive libmutton-based password managers call another instance of their executable with the `clipclear` argument (e.g. `mutn clipclear`) with the intended clipboard contents provided via STDIN. If after 30 seconds the clipboard contents have not changed, they are cleared. Please accept a `clipclear` argument that calls `core.ClipClearArgument()`.
