+In either the KDM window in the main DCP-o-matic, or the KDM creator, first add
+a new cinema by clicking <guilabel>Add Cinema...</guilabel>, giving it a name
+(perhaps the name of the distributor).
+</para>

+Then select this new cinema and click <guilabel>Add Screen...</guilabel> to open
+the screen dialog box, as shown in <xref linkend="fig-add-screen"/>.

+Here you can give any name (perhaps just ‘DKDM’). Then click <guilabel>Get from file...</guilabel>
+and choose the certificate file that the distributor gave you. Finally, click <guilabel>OK</guilabel>.

+Now you can create a KDM for this screen, and send it to the distributor. Using that KDM the distributor
+can then make KDMs for your DCP for anybody (and also, of course, decrypt the DCP if they wanted to).
