 ## Usage
 
 Using 2 colors and default (10) midpoints to generate an array of hex color values:
 
 ```javascript
-import colorGradient from "javascript-color-gradient";
+import { Gradient } from "javascript-color-gradient";
 
-const gradientArray = colorGradient.setGradient("#3F2CAF", "e9446a").getArray();
+const gradientArray = new Gradient()
+  .setColorGradient("#3F2CAF", "e9446a")
+  .getColors();
 
 console.log(gradientArray);
