The 30-second overview

Model — define content types (fields, references, validations, localization) in the visual builder. Assemblies compose pages from nested blocks via reference / reference_many fields.
Edit — authors work in a split view with live preview and inline editing, assisted by guideline-aware AI.
Deliver — published content is served by the delivery API with locale fallbacks and link resolution; drafts flow through preview tokens.

import { createClient } from '@ondros/sdk';

const client = createClient({
  host: 'http://localhost:8000',
  spaceId: '<space-id>',
  accessToken: 'cms_del_…',
});

const { items } = await client.getEntries({ contentType: 'article', limit: 10 });
