+# Contributing to Angular
+
+We would love for you to contribute to Angular and help make it even better than it is today!
+As a contributor, here are the guidelines we would like you to follow:
+
+ - [Code of Conduct](#coc)
+ - [Question or Problem?](#question)
+ - [Issues and Bugs](#issue)
+ - [Feature Requests](#feature)
+ - [Submission Guidelines](#submit)
+ - [Coding Rules](#rules)
+ - [Commit Message Guidelines](#commit)
+ - [Signing the CLA](#cla)
+
+
+## <a name="coc"></a> Code of Conduct
+
+Help us keep Angular open and inclusive.
+Please read and follow our [Code of Conduct][coc].
+
+
+## <a name="question"></a> Got a Question or Problem?
+
+Do not open issues for general support questions as we want to keep GitHub issues for bug reports and feature requests.
+Instead, we recommend using [Stack Overflow](https://stackoverflow.com/questions/tagged/angular) to ask support-related questions. When creating a new question on Stack Overflow, make sure to add the `angular` tag.
+
+Stack Overflow is a much better place to ask questions since:
+
+- there are thousands of people willing to help on Stack Overflow
+- questions and answers stay available for public viewing so your question/answer might help someone else
+- Stack Overflow's voting system assures that the best answers are prominently visible.
+
+To save your and our time, we will systematically close all issues that are requests for general support and redirect people to Stack Overflow.
+
+If you would like to chat about the question in real-time, you can reach out via [our gitter channel][gitter].
+
+
+## <a name="issue"></a> Found a Bug?
+
+If you find a bug in the source code, you can help us by [submitting an issue](#submit-issue) to our [GitHub Repository][github].
+Even better, you can [submit a Pull Request](#submit-pr) with a fix.
+
+
+## <a name="feature"></a> Missing a Feature?
+You can *request* a new feature by [submitting an issue](#submit-issue) to our GitHub Repository.
+If you would like to *implement* a new feature, please consider the size of the change in order to determine the right steps to proceed:
+
+* For a **Major Feature**, first open an issue and outline your proposal so that it can be discussed.
+  This process allows us to better coordinate our efforts, prevent duplication of work, and help you to craft the change so that it is successfully accepted into the project.
+
+  **Note**: Adding a new topic to the documentation, or significantly re-writing a topic, counts as a major feature.
+
+* **Small Features** can be crafted and directly [submitted as a Pull Request](#submit-pr).
+
+
+## <a name="submit"></a> Submission Guidelines
+
+
+### <a name="submit-issue"></a> Submitting an Issue
+
+Before you submit an issue, please search the issue tracker, maybe an issue for your problem already exists and the discussion might inform you of workarounds readily available.
+
+We want to fix all the issues as soon as possible, but before fixing a bug we need to reproduce and confirm it.
+In order to reproduce bugs, we require that you provide a minimal reproduction.
+Having a minimal reproducible scenario gives us a wealth of important information without going back and forth to you with additional questions.
+
+A minimal reproduction allows us to quickly confirm a bug (or point out a coding problem) as well as confirm that we are fixing the right problem.
+
+We require a minimal reproduction to save maintainers' time and ultimately be able to fix more bugs.
+Often, developers find coding problems themselves while preparing a minimal reproduction.
+We understand that sometimes it might be hard to extract essential bits of code from a larger codebase but we really need to isolate the problem before we can fix it.
+
+Unfortunately, we are not able to investigate / fix bugs without a minimal reproduction, so if we don't hear back from you, we are going to close an issue that doesn't have enough info to be reproduced.
+
+You can file new issues by selecting from our [new issue templates](https://github.com/angular/angular/issues/new/choose) and filling out the issue template.
+
+
+### <a name="submit-pr"></a> Submitting a Pull Request (PR)
+
+Before you submit your Pull Request (PR) consider the following guidelines:
+
+1. Search [GitHub](https://github.com/angular/angular/pulls) for an open or closed PR that relates to your submission.
+   You don't want to duplicate existing efforts.
+
+2. Be sure that an issue describes the problem you're fixing, or documents the design for the feature you'd like to add.
+   Discussing the design upfront helps to ensure that we're ready to accept your work.
+
+3. Please sign our [Contributor License Agreement (CLA)](#cla) before sending PRs.
+   We cannot accept code without a signed CLA.
+   Make sure you author all contributed Git commits with email address associated with your CLA signature.
+
+4. Fork the angular/angular repo.
+
+5. Make your changes in a new git branch:
+
+     ```shell
+     git checkout -b my-fix-branch master
+     ```
+
+6. Create your patch, **including appropriate test cases**.
+
+7. Follow our [Coding Rules](#rules).
+
+8. Run the full Angular test suite, as described in the [developer documentation][dev-doc], and ensure that all tests pass.
+
+9. Commit your changes using a descriptive commit message that follows our [commit message conventions](#commit).
+   Adherence to these conventions is necessary because release notes are automatically generated from these messages.
+
+     ```shell
+     git commit -a
+     ```
+    Note: the optional commit `-a` command line option will automatically "add" and "rm" edited files.
+
+10. Push your branch to GitHub:
+
+    ```shell
+    git push origin my-fix-branch
+    ```
+
+11. In GitHub, send a pull request to `angular:master`.
+
+   If we ask for changes via code reviews then:
+
+   * Make the required updates.
+   * Re-run the Angular test suites to ensure tests are still passing.
+   * Rebase your branch and force push to your GitHub repository (this will update your Pull Request):
+
+      ```shell
+      git rebase master -i
+      git push -f
+      ```
+
+That's it! Thank you for your contribution!
+
+
+#### After your pull request is merged
+
+After your pull request is merged, you can safely delete your branch and pull the changes from the main (upstream) repository:
+
+* Delete the remote branch on GitHub either through the GitHub web UI or your local shell as follows:
+
+    ```shell
+    git push origin --delete my-fix-branch
+    ```
+
+* Check out the master branch:
+
+    ```shell
+    git checkout master -f
+    ```
+
+* Delete the local branch:
+
+    ```shell
+    git branch -D my-fix-branch
+    ```
+
+* Update your master with the latest upstream version:
+
+    ```shell
+    git pull --ff upstream master
+    ```
+
+
+## <a name="rules"></a> Coding Rules
+To ensure consistency throughout the source code, keep these rules in mind as you are working:
+
+* All features or bug fixes **must be tested** by one or more specs (unit-tests).
+* All public API methods **must be documented**.
+* We follow [Google's JavaScript Style Guide][js-style-guide], but wrap all code at **100 characters**.
+
+   An automated formatter is available, see [DEVELOPER.md](docs/DEVELOPER.md#clang-format).
+
+
+## <a name="commit"></a> Commit Message Format
+
+*This specification is inspired and supersedes the [AngularJS commit message format][commit-message-format].*
+
+We have very precise rules over how our Git commit messages must be formatted.
+This format leads to **easier to read commit history**.
+
+Each commit message consists of a **header**, a **body**, and a **footer**.
+
+
+```
+<header>
+<BLANK LINE>
+<body>
+<BLANK LINE>
+<footer>
+```
+
+The `header` is mandatory and must conform to the [Commit Message Header](#commit-header) format.
+
+The `body` is mandatory for all commits except for those of scope "docs".
+When the body is required it must be at least 20 characters long.
+
+The `footer` is optional.
+
+Any line of the commit message cannot be longer than 100 characters.
+
+
+#### <a href="commit-header"></a>Commit Message Header
+
+```
+<type>(<scope>): <short summary>
+  │       │             │
+  │       │             └─⫸ Summary in present tense. Not capitalized. No period at the end.
+  │       │
+  │       └─⫸ Commit Scope: animations|bazel|benchpress|common|compiler|compiler-cli|core|
+  │                          elements|forms|http|language-service|localize|platform-browser|
+  │                          platform-browser-dynamic|platform-server|platform-webworker|
+  │                          platform-webworker-dynamic|router|service-worker|upgrade|zone.js|
+  │                          packaging|changelog|dev-infra|docs-infra|migrations|ngcc|ve
+  │
+  └─⫸ Commit Type: build|ci|docs|feat|fix|perf|refactor|style|test
+```
+
+The `<type>` and `<summary>` fields are mandatory, the `(<scope>)` field is optional.
+
+
+##### Type
+
+Must be one of the following:
+
+* **build**: Changes that affect the build system or external dependencies (example scopes: gulp, broccoli, npm)
+* **ci**: Changes to our CI configuration files and scripts (example scopes: Circle, BrowserStack, SauceLabs)
+* **docs**: Documentation only changes
+* **feat**: A new feature
+* **fix**: A bug fix
+* **perf**: A code change that improves performance
+* **refactor**: A code change that neither fixes a bug nor adds a feature
+* **style**: Changes that do not affect the meaning of the code (white-space, formatting, missing semi-colons, etc)
+* **test**: Adding missing tests or correcting existing tests
+
+
+##### Scope
+The scope should be the name of the npm package affected (as perceived by the person reading the changelog generated from commit messages).
+
+The following is the list of supported scopes:
+
+* `animations`
+* `bazel`
+* `benchpress`
+* `common`
+* `compiler`
+* `compiler-cli`
+* `core`
+* `elements`
+* `forms`
+* `http`
+* `language-service`
+* `localize`
+* `platform-browser`
+* `platform-browser-dynamic`
+* `platform-server`
+* `platform-webworker`
+* `platform-webworker-dynamic`
+* `router`
+* `service-worker`
+* `upgrade`
+* `zone.js`
+
+There are currently a few exceptions to the "use package name" rule:
+
+* `packaging`: used for changes that change the npm package layout in all of our packages, e.g. public path changes, package.json changes done to all packages, d.ts file/format changes, changes to bundles, etc.
+
+* `changelog`: used for updating the release notes in CHANGELOG.md
+
+* `dev-infra`: used for dev-infra related changes within the directories /scripts, /tools and /dev-infra
+
+* `docs-infra`: used for docs-app (angular.io) related changes within the /aio directory of the repo
+
+* `migrations`: used for changes to the `ng update` migrations.
+
+* `ngcc`: used for changes to the [Angular Compatibility Compiler](./packages/compiler-cli/ngcc/README.md)
+
+* `ve`: used for changes specific to ViewEngine (legacy compiler/renderer).
+
+* none/empty string: useful for `style`, `test` and `refactor` changes that are done across all packages (e.g. `style: add missing semicolons`) and for docs changes that are not related to a specific package (e.g. `docs: fix typo in tutorial`).
+
+
+##### Summary
+
+Use the summary field to provide a succinct description of the change:
+
+* use the imperative, present tense: "change" not "changed" nor "changes"
+* don't capitalize the first letter
+* no dot (.) at the end
+
+
+#### Commit Message Body
+
+Just as in the summary, use the imperative, present tense: "fix" not "fixed" nor "fixes".
+
+Explain the motivation for the change in the commit message body. This commit message should explain _why_ you are making the change.
+You can include a comparison of the previous behavior with the new behavior in order to illustrate the impact of the change.
+
+
+#### Commit Message Footer
+
+The footer can contain information about breaking changes and is also the place to reference GitHub issues, Jira tickets, and other PRs that this commit closes or is related to.
+
+```
+BREAKING CHANGE: <breaking change summary>
+<BLANK LINE>
+<breaking change description + migration instructions>
+<BLANK LINE>
+<BLANK LINE>
+Fixes #<issue number>
+```
+
+Breaking Change section should start with the phrase "BREAKING CHANGE: " followed by a summary of the breaking change, a blank line, and a detailed description of the breaking change that also includes migration instructions.
+
+
+### Revert commits
+
+If the commit reverts a previous commit, it should begin with `revert: `, followed by the header of the reverted commit.
+
+The content of the commit message body should contain:
+
+- information about the SHA of the commit being reverted in the following format: `This reverts commit <SHA>`,
+- a clear description of the reason for reverting the commit message.
+
+
+## <a name="cla"></a> Signing the CLA
+
+Please sign our Contributor License Agreement (CLA) before sending pull requests. For any code
+changes to be accepted, the CLA must be signed. It's a quick process, we promise!

-Do not open issues for general support questions as we want to keep GitHub issues for bug reports and feature requests.
+No abras *issues* para preguntas de soporte general ya que queremos mantener los *issues* de GitHub para reporte de *bugs* y solicitud de funcionalidades.
-Instead, we recommend using [Stack Overflow](https://stackoverflow.com/questions/tagged/angular) to ask support-related questions. When creating a new question on Stack Overflow, make sure to add the `angular` tag.
+En su lugar, recomendamos utilizar [Stack Overflow](https://stackoverflow.com/questions/tagged/angular) para hacer preguntas relacionadas con soporte. Al crear una nueva pregunta en Stack Overflow, asegúrate de agregar el etiqueta (tag) de `angular`.
 
-Stack Overflow is a much better place to ask questions since:
+Stack Overflow es mucho mejor para hacer preguntas ya que:
 
-- there are thousands of people willing to help on Stack Overflow
+- Hay miles de personas dispuestas a ayudar en preguntas y respuestas de Stack Overflow
-- questions and answers stay available for public viewing so your question/answer might help someone else
+que  permanecen disponibles para el público, por lo que tu pregunta o respuesta podría ayudar a otra persona.
-- Stack Overflow's voting system assures that the best answers are prominently visible.
+- El sistema de votación de Stack Overflow asegura que las mejores respuestas sobresalgan y sean visibles.
 
-To save your and our time, we will systematically close all issues that are requests for general support and redirect people to Stack Overflow.
+Para ahorrar tu tiempo y el nuestro, cerraremos sistemáticamente todos los *issues* que sean solicitudes de soporte general y redirigiremos a las personas a Stack Overflow.
 
-If you would like to chat about the question in real-time, you can reach out via [our gitter channel][gitter].
+Si deseas chatear sobre alguna pregunta en tiempo real, puedes hacerlo a través de nuestro [canal de Gitter][gitter].
 
 
-## <a name="issue"></a> Found a Bug?
+## <a name="issue"></a> ¿Encontraste un Bug?
 
-If you find a bug in the source code, you can help us by [submitting an issue](#submit-issue) to our [GitHub Repository][github].
+Si encontraste un error en el código fuente, puedes ayudarnos [creando un *issue*](#submit-issue) en nuestro [repositorio de GitHub][github].
-Even better, you can [submit a Pull Request](#submit-pr) with a fix.
+O incluso mejor, puedes [crear un *Pull Request*](#submit-pr) con la solución.
 
 
-## <a name="feature"></a> Missing a Feature?
+## <a name="feature"></a> ¿Falta alguna funcionalidad?
-You can *request* a new feature by [submitting an issue](#submit-issue) to our GitHub Repository.
+Puedes solicitar una nueva funcionalidad [creando un *issue*](#submit-issue) en nuestro repositorio de GitHub.
-If you would like to *implement* a new feature, please consider the size of the change in order to determine the right steps to proceed:
+Si deseas implementar una nueva funcionalidad, por favor considera el tamaño del cambio para determinar los pasos correctos para continuar:
 
-* For a **Major Feature**, first open an issue and outline your proposal so that it can be discussed.
+* Para un **cambio significativo**, primero abre un *issue* y describe tu propuesta para que pueda ser discutida.
-  This process allows us to better coordinate our efforts, prevent duplication of work, and help you to craft the change so that it is successfully accepted into the project.
+  Este proceso nos permite coordinar mejor nuestros esfuerzos, evitar trabajo duplicado y ayudarte a diseñar el cambio para que sea aceptado con éxito en el proyecto.
 
-  **Note**: Adding a new topic to the documentation, or significantly re-writing a topic, counts as a major feature.
+  **Nota**: Agregar un nuevo tema a la documentación o reescribir significativamente un tema, también cuenta como *cambio significativo*.
 
-* **Small Features** can be crafted and directly [submitted as a Pull Request](#submit-pr).
+* **Cambios pequeños** pueden ser elaborados y directamente [creados como un _pull request_](#submit-pr).

-Before you submit an issue, please search the issue tracker, maybe an issue for your problem already exists and the discussion might inform you of workarounds readily available.
+Antes de crear un *issue*, por favor busca en el el *issue tracker*, quizá un *issue* para tu problema ya existe y la discusión puede informarte sobre soluciones alternativas disponibles.
 
-We want to fix all the issues as soon as possible, but before fixing a bug we need to reproduce and confirm it.
+Queremos solucionar todos los problemas lo antes posible, pero antes de corregir un bug necesitamos reproducirlo y confirmarlo.
-In order to reproduce bugs, we require that you provide a minimal reproduction.
+Para reproducir errores, requerimos que proporciones una reproducción mínima.
-Having a minimal reproducible scenario gives us a wealth of important information without going back and forth to you with additional questions.
+Tener un escenario reproducible mínimo nos brinda una gran cantidad de información importante sin tener que ir y venir con preguntas adicionales.
 
-A minimal reproduction allows us to quickly confirm a bug (or point out a coding problem) as well as confirm that we are fixing the right problem.
+Una reproducción mínima nos permite confirmar rápidamente un bug (o señalar un problema de código), así también confirmar que estamos solucionando el problema correcto.
 
-We require a minimal reproduction to save maintainers' time and ultimately be able to fix more bugs.
+Requerimos una reproducción mínima para ahorrar tiempo a los encargados del mantenimiento y en última instancia, poder corregir más bugs.
-Often, developers find coding problems themselves while preparing a minimal reproduction.
+A menudo los desarrolladores encuentran problemas de código mientras preparan una reproducción mínima.
-We understand that sometimes it might be hard to extract essential bits of code from a larger codebase but we really need to isolate the problem before we can fix it.
+Entendemos que a veces puede ser difícil extraer porciones esenciales de código de un código más grande, pero realmente necesitamos aislar el problema antes de poder solucionarlo.
 
-Unfortunately, we are not able to investigate / fix bugs without a minimal reproduction, so if we don't hear back from you, we are going to close an issue that doesn't have enough info to be reproduced.
+Desafortunadamente no podemos investigar/corregir errores sin una reproducción mínima, por lo que si no tenemos tu retroalimentación del bug, vamos a cerrar el *issue* ya que no tiene suficiente información para reproducirse.
 
-You can file new issues by selecting from our [new issue templates](https://github.com/angular/angular/issues/new/choose) and filling out the issue template.
+Puedes presentar nuevos *issues* seleccionando nuestra [plantilla de _issues_](https://github.com/angular/angular/issues/new/choose) y complentando la plantilla.

-Before you submit your Pull Request (PR) consider the following guidelines:
+Antes de crear tu Pull Request (PR) considera los siguientes lineamientos:
 
-1. Search [GitHub](https://github.com/angular/angular/pulls) for an open or closed PR that relates to your submission.
+1. Busca en [GitHub](https://github.com/angular/angular/pulls) PRs que estén abiertos o cerrados y que estén relacionados con el que vas a crear.
-   You don't want to duplicate existing efforts.
+  No deseas duplicar los esfuerzos existentes.
 
-2. Be sure that an issue describes the problem you're fixing, or documents the design for the feature you'd like to add.
+2. Asegúrate de que el PR describa el problema que estás solucionando o que documente el diseño de la funcionalidad que deseas agregar.
-   Discussing the design upfront helps to ensure that we're ready to accept your work.
+   Discutir el diseño por adelantado ayuda a garantizar que estemos listos para aceptar tu trabajo.
 
-3. Please sign our [Contributor License Agreement (CLA)](#cla) before sending PRs.

-## Guide to authoring
+## Guía de autoría
+Existen dos tipos de contenido en la documentación:
 
-There are two types of content in the documentation:
+* **Documentación de API**: descripciones de los módulos, clases, interfaces, decoradores, etc que son parte de la plataforma Angular.
+La documentacion de API está generada directamente desde el código fuente.
+El código fuente está contenido en archivos TypeScript , almacenados en la carpeta `angular/packages`.
+Cada elemento de la API puede tener un comentario anterior, el cual contiene etiquetas y contenido de estilos JSDoc.
+El contenido está escrito en markdown.
 
-* **API docs**: descriptions of the modules, classes, interfaces, decorators, etc that make up the Angular platform.
+* **Otro contenido**: guias, tutoriales, y otro material de marketing.
-API docs are generated directly from the source code.
+Todos los demás contenidos se escriben utilizando markdown en archivos de texto, ubicados en la carpeta `angular/aio/content`.
-The source code is contained in TypeScript files, located in the `angular/packages` folder.
+Más específicamente, hay subcarpetas que contienen tipos particulares de contenido: guías, tutoriales y marketing.
-Each API item may have a preceding comment, which contains JSDoc style tags and content.
-The content is written in markdown.
 
-* **Other content**: guides, tutorials, and other marketing material.
+* **Ejempos de código**: los ejemplos de código deben ser comprobables para garantizar su precisión.
-All other content is written using markdown in text files, located in the `angular/aio/content` folder.
+Además, nuestros ejemplos tienen un aspecto específico y permiten al usuario copiar el código fuente. Para mayor
-More specifically, there are sub-folders that contain particular types of content: guides, tutorial and marketing.
+ejemplos se representan en una interfaz con pestañas (e.g. template, HTML, y TypeScript en pestañas separadas). Adicionalmente, algunos son ejemplos en acción, que proporcionan enlaces donde se puede editar el código, ejecutar, y/o descargar. Para obtener más detalles sobre cómo trabajar con ejemplos de código, lea los [fragmentos de código](https://docs.angular.lat/guide/docs-style-guide#code-snippets), [código fuente de marcado ](https://docs.angular.lat/guide/docs-style-guide#source-code-markup), y [ ejemplos en acción ](https://docs.angular.lat/guide/docs-style-guide#live-examples) paginas de los [ autores de guías de estilo ](https://docs.angular.lat/guide/docs-style-guide).
 
-* **Code examples**: code examples need to be testable to ensure their accuracy.
+Usamos la herramienta [dgeni](https://github.com/angular/dgeni) para convertir estos archivos en docs que se pueden ver en el doc-viewer.
-Also, our examples have a specific look and feel and allow the user to copy the source code. For larger

-tabs). Additionally, some are live examples, which provide links where the code can be edited, executed, and/or downloaded. For details on working with code examples, please read the [Code snippets](https://angular.io/guide/docs-style-guide#code-snippets), [Source code markup](https://angular.io/guide/docs-style-guide#source-code-markup), and [Live examples](https://angular.io/guide/docs-style-guide#live-examples) pages of the [Authors Style Guide](https://angular.io/guide/docs-style-guide).
 
-We use the [dgeni](https://github.com/angular/dgeni) tool to convert these files into docs that can be viewed in the doc-viewer.
+### Generando documentos completos
 
-The [Authors Style Guide](https://angular.io/guide/docs-style-guide) prescribes guidelines for
+La principal tarea para generar los documentos es `yarn docs`. Esto procesará todos los archivos fuente (API y otros), extrayendo la documentación y generando archivos JSON que pueden ser consumidos por el doc-viewer.
-writing guide pages, explains how to use the documentation classes and components, and how to markup sample source code to produce code snippets.
 
-### Generating the complete docs
+### Generación parcial de doc para editores
 
-The main task for generating the docs is `yarn docs`. This will process all the source files (API and other),
+La generación completa de documentos puede llevar hasta un minuto. Eso es demasiado lento para la creación y edición eficiente de documentos.
-extracting the documentation and generating JSON files that can be consumed by the doc-viewer.
 
-### Partial doc generation for editors
+Puedes ealizar pequeños cambios en un editor inteligente que muestre un markdown con formato:
+>En VS Code, _Cmd-K, V_ abre la vista previa de markdown en el panel lateral; _Cmd-B_ alterna la barra izquierda
 
-Full doc generation can take up to one minute. That's too slow for efficient document creation and editing.
+Puedes también mirar los cambios que se muestran correctamente en el doc-viewer
+con un tiempo de ciclo rápido de edición / visualización.
 
-You can make small changes in a smart editor that displays formatted markdown:
+Para este propósito, usa la tarea `yarn docs-watch`, que observa los cambios en los archivos de origen y solo vuelve a procesar los archivos necesarios para generar los documentos relacionados con el archivo que ha cambiado. 
->In VS Code, _Cmd-K, V_ opens markdown preview in side pane; _Cmd-B_ toggles left sidebar
+Dado que esta tarea tiene accesos directos, es mucho más rápido (a menudo menos de 1 segundo) pero no producirá contenido de fidelidad completa. Por ejemplo, los enlaces a otros documentoss y ejemplos de código pueden no mostrarse correctamente. Esto se nota especialmente en los enlaces a otros documentos y en los ejemplos incrustados, que no siempre se representan correctamente.
 
-You also want to see those changes displayed properly in the doc viewer
+La configuración general es la siguiente:
-with a quick, edit/view cycle time.
 
-For this purpose, use the `yarn docs-watch` task, which watches for changes to source files and only
+* Abrir una terminal, estar seguro que las dependencias están instaladas; ejecutar una generación inicial del doc; luego iniciar el doc-viewer:
-re-processes the files necessary to generate the docs that are related to the file that has changed.
-Since this task takes shortcuts, it is much faster (often less than 1 second) but it won't produce full
-fidelity content. For example, links to other docs and code examples may not render correctly. This is
-most particularly noticed in links to other docs and in the embedded examples, which may not always render
-correctly.
-
-The general setup is as follows:
-
-* Open a terminal, ensure the dependencies are installed; run an initial doc generation; then start the doc-viewer:
 
 ```bash
 yarn setup
 yarn start
 ```
 
-* Open a second terminal and start watching the docs
+* Abrir una segunda terminal e iniciar el observador de documentos.
 
 ```bash
 yarn docs-watch
 ```
 
->Alternatively, try the consolidated `serve-and-sync` command that builds, watches and serves in the same terminal window
+>Alternativamente, prueba el comando fusionado `serve-and-sync` que crea, observa y ejecuta en la misma ventana de la terminal
 ```bash
 yarn serve-and-sync
 ```
 
-* Open a browser at https://localhost:4200/ and navigate to the document on which you want to work.
+* Abre un navegador con la siguiente dirección https://localhost:4200/ y navega hasta el documento en el que quieras trabajar.
-You can automatically open the browser by using `yarn start -o` in the first terminal.
+Puedes automáticamente abrir el navegador utilizando `yarn start -o` en la primera terminal.
 
-* Make changes to the page's associated doc or example files. Every time a file is saved, the doc will
