 This gem wraps [the standalone executable version](https://github.com/sass/dart-sass/releases) of the Dart version of Sass. These executables are platform specific, but included in this gem are the ones for macOS, Linux, and Windows. The Linux and Windows versions are the ones for 64-bit, and the macOS version is compiled for Intel but will run on ARM as well.
 
-The installer will create your Sass input file in `app/assets/stylesheets/application.scss`. This is where you should import all the style files to be compiled [using the @use rule](https://sass-lang.com/documentation/at-rules/use). When you run `rails dartsass:build`, this input file will be used to generate the output in `app/assets/builds/application.css`. That's the output CSS that you'll include in your app.
+The installer will create your default Sass input file in `app/assets/stylesheets/application.scss`.

When you run `rails dartsass:build`, this input file will be used to generate the output in `app/assets/builds/application.css`. That's the output CSS that you'll include in your app. The load path for Sass is automatically configured to be `app/assets/stylesheets`.
 
-If you need to use a custom input or output file, you can run `bundle exec dartsass` to access the platform-specific executable, and give it your own build options.
+If you need to configure the build process – beyond configuring the build files – you can run `bundle exec dartsass` to access the platform-specific executable, and give it your own build options.
 
 When you're developing your application, you want to run Dart Sass in watch mode, so changes are automatically reflected in the generated CSS output. You can do this either by running `rails dartsass:watch` as a separate process, or by running `./bin/dev` which uses [foreman](https://github.com/ddollar/foreman) to starts both the Dart Sass watch process and the rails server in development mode.
