Vercel now supports the `vlt` package manager for builds with zero configuration in builds.

Starting today, Projects that contain a  `vlt-lock.json` file will automatically run `vlt install` as the default [Install Command](https://vercel.com/docs/concepts/deployments/build-step#install-command) using `vlt`.

`vlt` requires node `20.x` to run and is only available in the modern [build image](https://vercel.com/docs/builds/build-image).
