+
+Events:
+=======
+
+Events are substituted into the template either from a file or a remote ical
+calendar. Using an ical calendar is recommended as it allows defining recurring
+events.
+For using a remote calendar the events.js file should contain the following fields:
+
+{ "type": "ical",
+	"url": "https://sublab.org:5232/calendars/events",
+	"before": 0,
+	"after":  11160
+}
+
+The time offsets (seconds) are used to fetch past and future events from the
+calendar. All fields of each event are put into a div inside the event list
+element with the classes eventField and the name of the field. The example
+slideshows don't show those fields by default, but selectively enable known
+fields like summary and start time.
+
+Slides:
+=======
+
+Slides are created from each file in a subdirectory in the root directory
+defined in config.js (as described above). Slides consist of a media file
+(movies or images) and optionally a corresponding description. All media files
+should have the same size (at least with the default themes) to ensure a smooth
+transition between slides.
+Descriptions are defined in desc.js as follows:
+
+[
+	{
+		"file": "IMGP4596.jpg",
+		"head": "Kicker",
+		"text": "unser toller Profikicker"
+	},
+	{
+		"file": "IMG.jpg",
+		"head": "foobar",
+		"text": "barfoo"
+	}
+]
+
+The heading is put into a div inside the media tag (img or video) with the
+class slideHead. The description text is put into div inside the media tag with
+the class slideText.
