+
+## Browser support
+
+Angular uses the ["widely available" Baseline](https://web.dev/baseline) to define browser
+support. For each major version, Angular supports browsers included in the Baseline of a
+chosen date near the release date for that major.
+
+The "widely available" Baseline includes browsers released less than 30 months (2.5 years)
+of the chosen date within Baseline's core browser set (Chrome, Edge, Firefox, Safari) and
+targets supporting approximately 95% of web users.
+
+| Angular | Baseline Date | Browser Set                 |
+| ------- | ------------- | --------------------------- |
+| v21     | 2025-10-20    | [Browser Set][browsers-v21] |
+| v20     | 2025-04-30    | [Browser Set][browsers-v20] |
+
+[browsers-v21]: https://web-platform-dx.github.io/web-features/supported-browsers/?widelyAvailableOnDate=2025-10-20&includeDownstream=false
+[browsers-v20]: https://web-platform-dx.github.io/web-features/supported-browsers/?widelyAvailableOnDate=2025-04-30&includeDownstream=false
+
+Angular versions prior to v20 support the following specific browser versions:
+
+| Browser | Supported versions                          |
+| :------ | :------------------------------------------ |
+| Chrome  | 2 most recent versions                      |
+| Firefox | latest and extended support release \(ESR\) |
+| Edge    | 2 most recent major versions                |
+| Safari  | 2 most recent major versions                |
+| iOS     | 2 most recent major versions                |
+| Android | 2 most recent major versions                |
+
+## Polyfills
+
+Angular is built on the latest standards of the web platform.
+Targeting such a wide range of browsers is challenging because they do not support all features of modern browsers.
+You compensate by loading polyfill scripts \("polyfills"\) for the browsers that you must support.
+See instructions on how to include polyfills into your project below.
+
+IMPORTANT: The suggested polyfills are the ones that run full Angular applications.
+You might need additional polyfills to support features not covered by this list.
+
+HELPFUL: Polyfills cannot magically transform an old, slow browser into a modern, fast one.
+
+## Enabling polyfills with CLI projects
+
+The [Angular CLI](tools/cli) provides support for polyfills.
+If you are not using the CLI to create your projects, see [Polyfill instructions for non-CLI users](#polyfills-for-non-cli-users).
+
+The `polyfills` options of the [browser and test builder](tools/cli/cli-builder) can be a full path for a file \(Example: `src/polyfills.ts`\) or,
+relative to the current workspace or module specifier \(Example: `zone.js`\).
+
+If you create a TypeScript file, make sure to include it in the `files` property of your `tsconfig` file.
+
+```json
+
+{
+  "extends": "./tsconfig.json",
+  "compilerOptions": {
+    ...
+  },
+  "files": [
+    "src/main.ts",
+    "src/polyfills.ts"
+  ]
+  ...
+}
+```
+
+## Polyfills for non-CLI users
+
+If you are not using the CLI, add your polyfill scripts directly to the host web page \(`index.html`\).
+
+For example:
+
+<docs-code header="src/index.html" language="html">
+<!-- pre-zone polyfills -->
+<script src="node_modules/core-js/client/shim.min.js"></script>
+<script>
+  /**
+   * you can configure some zone flags which can disable zone interception for some
+   * asynchronous activities to improve startup performance - use these options only
+   * if you know what you are doing as it could result in hard to trace down bugs.
+   */
+  // __Zone_disable_requestAnimationFrame = true; // disable patch requestAnimationFrame
+  // __Zone_disable_on_property = true; // disable patch onProperty such as onclick
+  // __zone_symbol__UNPATCHED_EVENTS = ['scroll', 'mousemove']; // disable patch specified eventNames
+  /*
+   * in Edge developer tools, the addEventListener will also be wrapped by zone.js
+   * with the following flag, it will bypass `zone.js` patch for Edge.
+   */
+  // __Zone_enable_cross_context_check = true;
+</script>
+<!-- zone.js required by Angular -->
+<script src="node_modules/zone.js/bundles/zone.umd.js"></script>
+<!-- application polyfills -->
+</docs-code>

 ## Polyfills
 
-Angular is built on the latest standards of the web platform.
-Targeting such a wide range of browsers is challenging because they do not support all features of modern browsers.
-You compensate by loading polyfill scripts \("polyfills"\) for the browsers that you must support.
-See instructions on how to include polyfills into your project below.
+Angular está construido sobre los estándares más recientes de la plataforma web.
+Apuntar a una gama tan amplia de navegadores es un desafío porque no todos soportan todas las características de los navegadores modernos.
+Puedes compensar esto cargando scripts polyfill ("polyfills") para los navegadores que debes soportar.
+A continuación, encontrarás instrucciones sobre cómo incluir polyfills en tu proyecto.
 
-IMPORTANT: The suggested polyfills are the ones that run full Angular applications.
-You might need additional polyfills to support features not covered by this list.
+IMPORTANTE: Los polyfills sugeridos son los que ejecutan aplicaciones Angular completas.
+Es posible que necesites polyfills adicionales para soportar características no cubiertas por esta lista.
 
-HELPFUL: Polyfills cannot magically transform an old, slow browser into a modern, fast one.
+ÚTIL: Los polyfills no pueden transformar mágicamente un navegador antiguo y lento en uno moderno y rápido.
 
-## Enabling polyfills with CLI projects
+## Habilitando polyfills en proyectos CLI
 
-The [Angular CLI](tools/cli) provides support for polyfills.
-If you are not using the CLI to create your projects, see [Polyfill instructions for non-CLI users](#polyfills-for-non-cli-users).
+El [Angular CLI](tools/cli) proporciona soporte para polyfills.
+Si no estás usando el CLI para crear tus proyectos, consulta las [Instrucciones de polyfills para usuarios sin CLI](#polyfills-para-usuarios-sin-cli).
 
-The `polyfills` options of the [browser and test builder](tools/cli/cli-builder) can be a full path for a file \(Example: `src/polyfills.ts`\) or,
-relative to the current workspace or module specifier \(Example: `zone.js`\).
+La opción `polyfills` del [builder de navegador y pruebas](tools/cli/cli-builder) puede ser una ruta completa de un archivo \(Ejemplo: `src/polyfills.ts`\) o,
+relativa al espacio de trabajo actual o especificador de módulo \(Ejemplo: `zone.js`\).
 
-If you create a TypeScript file, make sure to include it in the `files` property of your `tsconfig` file.
+Si creas un archivo TypeScript, asegúrate de incluirlo en la propiedad `files` de tu archivo `tsconfig`.

-## Polyfills for non-CLI users
+## Polyfills para usuarios sin CLI
 
-If you are not using the CLI, add your polyfill scripts directly to the host web page \(`index.html`\).
+Si no estás usando el CLI, agrega tus scripts polyfill directamente a la página web host \(`index.html`\).
