So I have an existing frontend Git repo that's probably pretty compatible with v0, but it wasn't created in v0. It would be essentially hooking up an existing system that doesn't have test data to show in the same way that a typical v0 prototype works. I'm wondering what are the best practices in how to do that, or is it even possible? Can I basically add a v0 view on the repo which then just forks versions of it, makes changes, abides by the Guidelines and the storybook design patterns and all those sorts of things? Can I just start using v0 atop my existing Git repo, or is that usually not a successful way to do it and you kind of have to do it from the get-go? Just curious on your thoughts and best practices on this topic
