+Base configuration file to configure a station on liquidsoap.
+
+A Station is composed of multiple streams, that includes:
+- controller.dealer: used to play scheduled programs;
+- controller.streams: streams configured to play random sounds;
+
+# Interactive elements:
+An interactive element is accessible to the people, in order to:
+- get metadata
+- skip the current sound
+- enable/disable it, only for the dealer
+
+- {controller.id}: the station itself
+- {controller.id}_streams: all the streams of a controller
+- {source.id}: for each stream of a controller + dealer
+
+
+# Element of the context
+We use theses elements from the template's context:
+- controller: controller describing the station itself
+- settings: global settings
+
+# Overwrite the template
+It is possible to overwrite the template, there are blocks at different
+position in order to do it. Keep in mind that you might want to avoid to
+put station specific configuration in the template itself.
