+
+<para>
+It can be inconvenient to need a whole DCP-o-matic project just to
+create KDMs for its film.  Perhaps you want to archive the project to
+save space, or create KDMs on a different machine.  In such situations
+it is easier to use a DKDM.  This is a normal KDM, but instead of
+being targeted at a projection system (to allow it to decrypt the
+content) it is targeted at a particular users's certificate.  This
+means that the certificate owner can create new KDMs for other users.
+The DKDM holds everything that is required to create further KDMs.
+</para>
+
+<para>
+Sometimes it is useful to create DKDMs that can be used by
+DCP-o-matic.  If you create such a DKDM you can keep it and then, at
+any point in the future, use DCP-o-matic's standalone KDM creator to
+make KDMs for the DKDM's film for any cinema.
+</para>
+
+<para>
+In other cases a DKDM is sent to a 3rd party so that they can create
+KDMs for your films.  This can be useful if, for example, you have a

+KDMs for anybody that requires them at short notice.
