 moodle-filter_opencast
 =====================
-The opencast filter can be used to embed opencast videos.
+The opencast filter can be used to embed opencast videos in Moodle.
+Mainly it is used in combination with the opencast repository plugin to play videos in course text fields.
+
+
+Description
+-----------
 The filter takes the HTML pasted by the opencast repository and replaces it by an iframe, which loads the [Paella Player 7](https://paellaplayer.upv.es/) with the respective opencast event.
 The filter itself has no influence on the embedded content, but simply takes the information created by the repository.
 Look into the documentation of [repository_opencast](https://github.com/Opencast-Moodle/moodle-repository_opencast) for details on that.
