-If you have Rails Engines in your application that use Tailwind CSS and provide an `app/assets/tailwind/<engine_name>/engine.css` file, entry point files will be created for each of them in `app/assets/builds/tailwind/<engine_name>.css` so they can be included in your host application's Tailwind CSS by adding `@import "../builds/tailwind/<engine_name>"` to your `app/assets/tailwind/application.css` file.
+If you have Rails Engines in your application that use Tailwind CSS and provide an `app/assets/tailwind/<engine_name>/engine.css` file, entry point files will be created for each of them in `app/assets/builds/tailwind/<engine_name>.css` on the first build/watch invocation or manual call for `rails tailwindcss:engines` so they can be included in your host application's Tailwind CSS by adding `@import "../builds/tailwind/<engine_name>"` to your `app/assets/tailwind/application.css` file.
 
 > [!IMPORTANT]
 > You must `@import` the engine CSS files in your `app/assets/tailwind/application.css` for the engine to be included in the build. By default, no engine CSS files are imported, and you must opt-in to using the file in your build.
