+=head1 NAME
+
+luksformat - Create and format an encrypted LUKS device
+
+=head1 SYNOPSIS
+
+B<luksformat> [B<-t> I<fstype>] I<device> [ mkfs options ]
+
+=head1 DESCRIPTION
+
+B<luksformat> is a wrapper around B<cryptsetup> and B<mkfs> which provides an
+easy interface for creating an encrypted device that follows the LUKS standard
+and for putting a file system onto the encrypted device.
+
+The default file system is B<vfat> since that is most commonly used on
+removable devices. However, you can specify any available file system with the
+B<-t> option.
+
