# Overview

- [Getting started](https://www.i18next.com/overview/getting-started.md): Install i18next with npm or a CDN script, initialize it with resources, and call t() in Node.js, the browser or any framework.
- [Comparison to others](https://www.i18next.com/overview/comparison-to-others.md): Why i18next: sustainability, maturity, extensibility and richness, and answers to the claims that it is complicated, bloated or too big.
- [API](https://www.i18next.com/overview/api.md): Reference for the i18next API: init, use, t, exists, changeLanguage, loadNamespaces, addResourceBundle, events and the other instance methods.
- [Configuration Options](https://www.i18next.com/overview/configuration-options.md): Every option of i18next.init: languages and fallbacks, namespaces, resources, saveMissing, interpolation, plurals, detection and backend settings.
- [Supported Frameworks](https://www.i18next.com/overview/supported-frameworks.md): Framework bindings and integrations for i18next: React, Vue, Angular, Svelte, Solid, Next.js, Express, Deno, jQuery and more, maintained by their authors.
- [Plugins and Utils](https://www.i18next.com/overview/plugins-and-utils.md): The i18next plugin ecosystem: i18n formats, extraction tools, utilities, services, backends and backend extenders, language detectors and post processors.
- [Translation Management Systems](https://www.i18next.com/overview/translation-management-systems.md): How translation management systems integrate with i18next (saveMissing, i18next-cli, CDN delivery), compared on i18next criteria. Locize is the TMS built by the i18next maintainers.
- [For Enterprises](https://www.i18next.com/overview/for-enterprises.md): Why the library alone is not a localization process: what a product team needs for translation, review and continuous delivery, and how Locize, built by the i18next team, covers it.

- [TypeScript](https://www.i18next.com/overview/typescript.md): Type-safe keys with i18next: the declaration file and CustomTypeOptions, the selector API, per-package namespace types in monorepos, testing and troubleshooting.
