# @roottale/cms-core

RootTale CMS core — Block JSON schema (Gutenberg/Tiptap-compatible), serialize, validate.

Transitive dependency of [`@roottale/cms-renderer-next`](https://www.npmjs.com/package/@roottale/cms-renderer-next) and [`@roottale/cms-renderer-astro`](https://www.npmjs.com/package/@roottale/cms-renderer-astro). You usually don't install this directly — the renderer pulls it in. Install standalone if you need the types/schema in your own pipeline (custom validators, content migrations, codegen).

See ADR-0034 §3 §5 for the schema decision context.

```bash
npm install @roottale/cms-core
