You can now add autocompletion, type checking, schema validation, and in-editor documentation to any `vercel.json` file.

Add `https://openapi.vercel.sh/vercel.json` as the `$schema` key at the top of your file. The schema file is autogenerated similar to our [automatic REST API documentation](https://vercel.com/changelog/automatic-rest-api-documentation-with-openapi).

Check out [the documentation](https://vercel.com/docs/cli#project-configuration) as well.
