　　Getting started

　　The Color Thief package includes multiple distribution files to support different environments and build processes. Here is the list of all the files in the /dist folder and what formats they support:

　　color-thief.js - CommonJS module for use in Node.

　　color-thief.mjs - ES6 module. For modern browsers as well as Webpack and Rollup.

　　color-thief.umd.js - UMD module. For simple script tag loading that exposes a global variable or for RequireJS AMD support.

　　color-thief.min.js - Duplicate of color-thief.umd.js. Kept around to maintain backwards compatibility.
