Is reading teacher notes important

You don't have to necessarily read the links, to understand the principles learned in the Treehouse courses, but it is good to familiarize yourself with looking through the documentations and resources, because that is how you will be using these concepts when you go to code your websites.

You will not be able to fully grasp and retain ALL of the knowledge learned in these courses, but you are learning how to research API and element documentation to use in the real world.

While you do not have to read the links to pass these courses, you will need them in the future.

When you start coding a login form that you only want to display in the header, you will have to know where to look for the information you need to achieve this.

If you don't spend the time learning the actual research methods used in coding, you don't actually learn how to code, because you will not be able to remember syntax and terminology by heart.
