-## Requirements
-
-Use the module in [environments with ES6 support](https://kangax.github.io/compat-table/es6/).

-If you use ES modules, you may import the potprox module from the [potprox.min.mjs](dist/potprox.min.mjs) file:
+If you need only a few potential classes, using named import will allow module bundlers to perform “tree shaking” and exclude the rest unused code.
 
 ```javascript

 ## Usage
 
 Here is an example of approximation of some external computational data using the potprox module.
 
 ```javascript
-let potprox = require("potprox");
+import * as potprox from "potprox";
