-Adds [UglifyJS](https://github.com/mishoo/UglifyJS2) support to
-[brunch](http://brunch.io).
+Adds [Terser](https://github.com/terser-js/terser) support to [Brunch](http://brunch.io).
 
-The plugin will minify your javascript files.
+The plugin will minify your JavaScript files. Supports modern language features.
 
-## Usage
-
-Install the plugin via npm with `npm install --save-dev uglify-js-brunch`.
+Previously known as `uglify-js-brunch`.
 
-Or, do manual install:
+## Usage
 
-* Add `"uglify-js-brunch": "x.y.z"` to `package.json` of your brunch app. Pick a plugin version that corresponds to your minor (y) brunch version.
-* If you want to use git version of plugin, add
-`"uglify-js-brunch": "git+ssh://git@github.com:brunch/uglify-js-brunch.git"`.
+Install the plugin via npm with `npm install --save-dev terser-brunch`.
 
-To specify UglifyJS options, use `config.plugins.uglify` object, for example:
+To specify [Terser options](https://github.com/terser-js/terser#minify-options), use `config.plugins.terser` object, for example:
 
 ```js
 module.exports = {
