+<guilabel>Jobs</guilabel> menu. Before encoding your DCP, DCP-o-matic
+will run a series of checks on your film to look for various conditions
+that might cause problems when playing back the DCP. If any potential
+problems are found, DCP-o-matic will show you a list of hints.
+Each hint describes the condition that was found and gives
+advice on how to resolve it. If hints are found and reported, you can
+either <guilabel>Make DCP</guilabel> anyway (without adjusting any
+settings), or <guilabel>Go back</guilabel> in order to make
+adjustments before encoding the DCP.

+<para>
+If no hints were found (or you pressed <guilabel>Make DCP</guilabel>
+after hints were displayed), DCP-o-matic will encode your DCP.
This may take some time (many hours in some cases). While the job is
in progress, DCP-o-matic will update you on how it is getting on with
the progress bar in the bottom of its window, as shown in <xref

+<title>Creating KDMs for a distributor</title>
+
+<para>
+Sometimes you have an encrypted DCP and you want to allow somebody else
+(for example, a distributor) to make KDMs for the DCP on your behalf.
+</para>
+
+<para>
+The normal way to do this is to send the distributor a KDM which they
+can use with their own KDM creation system. Such a KDM is often called
+a DKDM (the ‘D’ stands for <emphasis>Distribution</emphasis>).
+It is the same as a normal KDM except that it is made to work with another
+computer, rather than with a projection system.
+</para>
+
+<para>
+To make a DKDM for a distributor you will first need to ask them to send you
+a decryption certificate. This should be a small file, usually with the extension
+<code>.pem</code>.
+</para>
+
+<para>
+Once you have the certificate, you will need to add a ‘fake’ cinema
+and screen to the list in DCP-o-matic. This is because making a KDM for another
+computer uses the same process internally as making one for a projection system,
+it's just that DCP-o-matic does not have a nice way to present that.
+</para>
+
+<para>
+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>
+
+<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"/>.
+</para>
+
+<figure id="fig-add-screen">

+ <imageobject>
+ <imagedata scale="30" fileref="screenshots/add-screen&scs;"/>
+ </imageobject>
+ </mediaobject>
+</figure>
+
+<para>
+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>.
+</para>
+
+<para>
+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).
