Before you begin

This course is based on a set of lectures that I created somewhere in mid-2018. Some of the material is dated - but not because my view on the learning sequence has changed. (except for one small change - I figured out a way for non-programmers to learn about webhooks without writing code, so you might notice that as you go through the videos).

Rather, it is because some of the resources I mention in the videos are not available (and may become unavailable in the future) - some of them have become completely free, sometimes I have consolidated them into a different resource, sometimes I have expanded it into more material etc.

As you view these videos, please make sure you look at the Resources section (i.e. the text under the video) which usually provides more up-to-date information.
