What does preservedFiles do in jambo.json file

What does preservedFiles in jambo.json file do? What’s a use case where I’d want to include something here?

Hey Liz,

If you’ve manually added an artifact to desktop, such as robots.txt, it should be included in preservedFiles. Presumably, this artifact is static and can’t be generated by Jambo or the Theme. When Jambo’s build command is run, it first deletes everything in desktop, save for whatever is listed in preservedFiles. The assumption is that whatever is deleted will be re-generated during the build process.
