 ## File structure
 
 Whenever possible, avoid modifying Bootstrap's core files. For Sass, that means creating your own stylesheet that imports Bootstrap so you can modify and extend it. Assuming you're using a package manager like npm, you'll have a file structure that looks like this:

    Here's a recap of why we need all these loaders. `style-loader` injects the CSS into a `<style>` element in the `<head>` of the HTML page, `css-loader` helps with using `@import` and `url()`, `postcss-loader` is required for Autoprefixer, and `sass-loader` allows us to use Sass.
