 + When running a function app on Windows, the app setting `WEBSITE_RUN_FROM_PACKAGE = <URL>` gives worse cold-start performance and isn't recommended.
 + When you specify a URL, you must also [manually sync triggers](functions-deployment-technologies.md#trigger-syncing) after you publish an updated package.
 + The Functions runtime must have permissions to access the package URL.
