 > A simple and customizable markdown CSS stylesheet for everyone.
 
-## Requirement
+## Browsers Support
+
+According to [.browserslistrc](https://github.com/kuohuanhuan/x-markdown-css/blob/master/.browserslistrc), `x-markdown-css` supports **all browsers support CSS variables.**
+
+## Usage
+
+You can use `x-markdown-css` with:
+
+1. A CDN service:
+
+- UNPKG: `https://unpkg.com/x-markdown-css@latest/dist/bundle.min.css`
+- jsDelivr: `https://fastly.jsdelivr.net/npm/x-markdown-css@latest/dist/bundle.min.css`
+- CDNJS: *Coming soon. **Waiting for you to make `x-markdown-css` [popular enough](https://github.com/cdnjs/packages/blob/master/CONTRIBUTING.md#policy-rules-and-guidelines)**!*
+
+> *ps. Note that `bundle.css` without `.min` stands for unminified version.*
+
+2. A CSS (with Node.js) / Sass / SCSS project:
+
+First, install it with NPM ([PNPM](https://pnpm.io) or [Yarn](https://yarnpkg.com) also works):
+
+```sh
+npm i x-markdown-css@latest
+```
+
+Then, add it to your `.css` / `.sass` / `.scss` file.
+
+For example, in CSS / SCSS you do:
+
+```css
+@import 'x-markdown-css';
+```
+
+> *ps. Note that no path or file extention is required
+> since the `style` and `sass` field in `package.json` is filled.  
+> Just simply use `'x-markdown-css'` to import it.*
+
+## Built with
+
+The following tools and suite libraries made the development of `x-markdown-css` possible:
+
+- [SCSS](https://sass-lang.com)
+- [Stylelint](https://stylelint.io)
+- [Grunt](https://gruntjs.com)
+- [PostCSS](https://postcss.org)
+- [cssnano](https://cssnano.co)
+
+*...and much more.*
