Support for non Kit Svelte Projects

[negue]

I just wanted to try to install tailwind with the cli

npx sv add tailwindcss

but this resulted in

Welcome to the Svelte CLI! (v0.8.6)

Is there maybe a workaround to get the CLI working with adding properties / configs somewhere?

I tried adding kit.libDirectory to the svelte.config.js but that sadly didn't help 😅
