+Output files
+===========
+
+The Ship Traffic Generator creates output files according to
+the open-source `maritime schema`_ `Traffic Situation`_ format.
+
+.. _maritime schema: https://dnv-opensource.github.io/maritime-schema/
+.. _Traffic Situation: https://dnv-opensource.github.io/maritime-schema/traffic_situation/
+
+Below is one example of an output file created by the Ship Traffic Generator.
+This describes the starting position of the ownship (ship under test)
+and one target ship, and their planned goal positions, for a head-on (HO) encounter.
+Note that the first waypoint is typically set to the initial waypoint.
+The `targetShips` field can contain multiple target ships,
+at different COLREG encounter courses.
+
+Example 1: Output file generated by the Ship Traffic Generator::

 ~~~~~~~~~~
 When generating situations without specifying where the desired situations (``--situation``) are found, the

 Baseline situations
 ~~~~~~~~~~~~~~~~~~~
 The baseline situations are a set of generic traffic situations covering head-on, overtaking stand-on/give-way
 and crossing stand-on/give-way encounters. To cover the combination of encounters for 1, 2 and 3 target ships,
