Install, set up, configure, or integrate CKEditor 5 — the rich-text / WYSIWYG editor — in any JavaScript project. Covers the `ckeditor5` and `ckeditor5-premium-features` npm packages, the CKEditor CDN/cloud build, and ZIP/self-hosted builds, in vanilla JS or any framework (React, Vue, Angular, Next.js, Nuxt, Svelte, Astro, plain HTML). Use when adding an editor, wiring the editor component, choosing an install method, configuring plugins / toolbar / menu bar / editor type (classic, inline, balloon, decoupled, multi-root), loading editor CSS, setting the license key (`GPL` or commercial), starting a free trial, or unlocking premium features (collaboration, comments, track changes, revision history, CKEditor AI, import/export to Word/PDF, pagination, CKBox). Also for fixing setup errors: duplicated modules, missing/broken styles, license-key errors, or SSR `window is not defined`. NOT for authoring custom plugins, upgrading versions, fixing breaking changes, or CKEditor 4.
