+## Differences from the Original Package
 
+This is a fork of [rook2pawn/node-easing](https://github.com/rook2pawn/node-easing) with the following changes:
+- Transpile source files with Babel
+- Create a library build using Webpack + babel-loader
+
+### Motivation
+
+As distributed, the original project's source files, including [rook2pawn/node-easing/browser-easing.js](https://github.com/rook2pawn/node-easing/blob/3a78daa45cb9f0f85f0acae1919e8a12594149f7/browser-easing.js#L16), are not valid ES5. This leads to knock-on issues, such as when bundling the library with a tool that uses [UglifyJS](https://github.com/mishoo/UglifyJS):
+
+<details><summary>Error from UglifyJS Showing "Unexpected token operator «=»" in browser-easing.js</summary>
+
+```
+js/main-ec3d69cc.js from UglifyJs
+Unexpected token operator «=», expected punc «,» [../node_modules/easing/browser-easing.js:8,0][js/main-ec3d69cc.js:28118,46]
+```
+</details>
+
+Hence, this fork transpiles the source files to valid ES5:
+
+- The **lib** folder contains individual transpiled source files
+- **browser-easing.js**, a UMD module as before, is also transpiled
