+Welcome to educational Bitcoin videos. The purpose of this course is to provide
+an introduction to Bitcoin. It is divided into three bigger parts, each
+consisting of three or four smaller short videos. You can consume these videos
+easily when you have a bit of free time and rewatch them for better understanding.
+
+Part one is about the theory of Bitcoin. What it is or isn't, what you can do
+with it or can't do with it, and what you should or shouldn't do with it.
+
+Part two is about using Bitcoin on your mobile phone.
+
+Part three is about using Bitcoin with a secure device.
