Welcome to the course
To watch the video, click the play button (arrow).
Closed Captions (subtitles) are available on this video. To view them click the (CC) button at the bottom right-hand corner of the video screen and select 'English'. AI-generated captions are available in other languages as well, but I can't guarantee their accuracy.
When you have finished watching the video click the green 'complete and continue' button* at the top of the screen to move to the next lecture.
*If you are on a mobile device the green button will simply have an arrow on it.
