 Use [Bun](https://bun.sh), [esbuild](https://esbuild.github.io), [rollup.js](https://rollupjs.org), or [Webpack](https://webpack.js.org) to bundle your JavaScript, then deliver it via the asset pipeline in Rails. This gem provides installers to get you going with the bundler of your choice in a new Rails application, and a convention to use `app/assets/builds` to hold your bundled output as artifacts that are not checked into source control (the installer adds this directory to `.gitignore` by default).
 
-You develop using this approach by running the bundler in watch mode in a terminal with `yarn build --watch` (and your Rails server in another, if you're not using something like [puma-dev](https://github.com/puma/puma-dev)). You can also use `./bin/dev`, which will start both the Rails server and the JS build watcher (along with a CSS build watcher, if you're also using `cssbundling-rails`).
+You develop using this approach by running the bundler in watch mode in a terminal with `npm run build -- --watch` (and your Rails server in another, if you're not using something like [puma-dev](https://github.com/puma/puma-dev)). You can also use `./bin/dev`, which will start both the Rails server and the JS build watcher (along with a CSS build watcher, if you're also using `cssbundling-rails`).
 
 Whenever the bundler detects changes to any of the JavaScript files in your project, it'll bundle `app/javascript/application.js` into `app/assets/builds/application.js` (and all other entry points configured). You can refer to the build output in your layout using the standard asset pipeline approach with `<%= javascript_include_tag "application", defer: true %>`.
