+
+The colours will be automatically determined from the event and track
+colours set inside pretalx.
+
+You can also add a configurable third line to the lower thirds, for
+example to hint your audience to vote for the talks. To make this easier,
+the plugin will automatically replace some placeholders inside the text,
+so you can have individual text for all talks.
