Massive effort getting through the first section! There was a lot to go through and if you're thinking, "wow this is too much...", don't worry, you're not alone. Machine learning is broad and learning a new skill takes time.

One place you might want to check out for some auxiliary learning whilst you go through the rest of this course is the Elements of AI website.

It's got some great introductory explanations of many of the concepts involved in machine learning, data science and artificial intelligence.

Of course, going through the Elements of AI material is completely optional. But if you need a break from coding (we'll be doing plenty of it), remember it's always there.

Now you've had an introduction to machine learning, let's get your computer set up for it!
