+### Schedule/Program
-=== Schedule/Program
+Our semi-automated editing platform needs the program/schedule in
+schedule.xml format. These file are produced by the usual conference
+planning solutions (frab, pretalx, ...) without needing to configure
+anything. If you want to use pretalx, but don't have the means to run
+your own instance, you can use
+[the c3voc pretalx instance](https://pretalx.c3voc.de) or
+[pretalx hosted](https://pretalx.com).

+required. We do require IPv4 connectivity, but a NATed connection is
+fine.
-=== Network
+Due to the nature of the infrastructure, we cannot provide you with a
+list of ip addresses we need to connect to. If your network does have
+restrictions, please ensure we can reach the whole internet on these
+ports:

-=== Insurance
+### Insurance
-The organiser has to insure our hardware for damages and theft during the event and relevant transportation from/to the event. Since the hardware is relatively expensive (roughly 16.000EUR per case) this is usually handled by an event insurance which most organizers will already have. When necessary we can supply relevant serial numbers, please get in contact if needed. See [[eventhowto#anlieferung_versicherung]] for more information on this topic.
