 ### Manage your static files and assets
 
-Static files are configured with [environment variables](#setting-up-environment-variables-on-clever-cloud):
-
-`STATIC_FILES_PATH`: should point to a directory where your static files are stored.
-
-`STATIC_URL_PREFIX`: the URL path under which you want to serve static files (for example `/public/`)
-
-**Note**: the path of your folder must be absolute regarding the root of your application.
-
-**Note**: setting the `STATIC_URL_PREFIX` to `/` will make the deployment to fail.
-
-If you use the asset pipeline, make sure to include the `assets:precompile` task in the `CC_RAKEGOALS` environment variable value.
+For a standard Rails application using the asset pipeline, you typically do not need to set `STATIC_FILES_PATH` or `STATIC_URL_PREFIX`. Rails serves assets through the application itself. Make sure to include the `assets:precompile` task in the `CC_RAKEGOALS` environment variable value:
 
 ```bash
 CC_RAKEGOALS="db:migrate, assets:precompile"
 ```
 
-**Note**: if your project uses `webpacker`, make sure to enable the dedicated build instance option in the **Information** menu of your application in the Clever Cloud console because `webpacker` needs a lot a resources when starting.
+If you need NGINX to serve static files directly (for example, for a non-Rails Rack application), configure these [environment variables](#setting-up-environment-variables-on-clever-cloud):
+
+`STATIC_FILES_PATH`: should point to a directory where your static files are stored. The path must be absolute regarding the root of your application.
+
+`STATIC_URL_PREFIX`: the URL path under which you want to serve static files (for example `/public/`). If not set, NGINX serves common static file extensions automatically.
