Why this course?

Description

SDC implements the single directory component approach. Everything you need for your component is in a single directory.

This includes: my-component.twig, my-styles.css, my-behaviors.js, my-component.php, etc. If it affects how your component renders, it's in that directory

This way your components are easier to find, don't have unaccounted code on some other place, and can be easily copy&pasted.
