+## Instalation
+You can use RFS in your project by installing it using a package manager (recommended):
+
+**npm:**
+
+```
+$ npm install rfs --save
+```
+
+**yarn:**
+
+```
+$ yarn add rfs
+```
+
+**Bower:**
+
+```
+$ bower install rfs --save
+```
+
+**Copy/paste (not recommended):**
+
+You can download the RFS SCSS-file and save it in your `scss/` directory. This
+method is not recommended because you lose the ability to easily and quickly
+manage and update RFS as a dependency.

 ## About
-RFS stands for Responsive Font-Size, easy to remember, easy to use. It’s a desktop-first approach which **automatically calculates the correct font-size** for every screen width. Desktop-first approach means you just have got to define your font-size for big screens and the font-size will automatically decrease for smaller screens. RFS is a **SCSS-mixin** which generates the responsive css for you.
