How to add Shadcn to exisiting mono-repos?

[alamenai]

I have already a mono repo and I want to start using Shadcn CLI but it is only for fresh projects, is there a way how to add it to an existing mono-repos:

 npx shadcn@canary init
✔ Preflight checks.
✖ Verifying framework.

We could not detect a supported framework at /home/aldin-bug/Desktop/one-night.
Visit https://ui.shadcn.com/docs/installation/manual to manually configure your project.
Once configured, you can use the cli to add components.
