 * Create PRs that cover only **one specific issue/solution/bug**. Do not create PRs that are huge monoliths and could have been split into multiple independent contributions.
 * NewPipe uses [NewPipeExtractor](https://github.com/TeamNewPipe/NewPipeExtractor) to fetch data from services. If you need to change something there, you must test your changes in NewPipe. Telling NewPipe to use your extractor version can be accomplished by editing the `app/build.gradle` file: the comments under the "NewPipe libraries" section of `dependencies` will help you out.
 
+### Kotlin in NewPipe
+* NewPipe will remain mostly Java for time being
+* Contributions containing a simple conversion from Java to Kotlin should be avoided. Conversions to Kotlin should only be done if Kotlin actually brings improvements like bug fixes or better performance which are not, or only with much more effort, implementable in Java. The core team sees Java as an easier to learn and generally well adopted programming language.

 ### Creating a Pull Request (PR)
 
 * Make changes on a **separate branch** with a meaningful name, not on the _master_ branch or the _dev_ branch. This is commonly known as *feature branch workflow*. You may then send your changes as a pull request (PR) on GitHub.

+## Instalación y Actualizaciones
 
-## Installación y actualizaciones
 Se puede instalar NewPipe usando uno de los métodos siguientes:
- 1. Agregar nuestro repositorio personalizado a F-Droid e instalarlo desde allí. Las instrucciones están aquí: https://newpipe.net/FAQ/tutorials/install-add-fdroid-repo/
- 2. Descargar el archivo APK del enlace [Github Releases](https://github.com/TeamNewPipe/NewPipe/releases) e instalarlo.
- 3. Actualizar a través de F-Droid. Este es el método más lento para obtener la actualización, como F-Droid debe reconocer cambios, construir el APK aparte, firmarlo con una clave, y finalmente empujar la actualización a los usuarios.
- 4. Construir un APK de depuración por si mismo. Este es el modo más rápido para realizar nuevas características en su dispositivo, pero es mucho más complicado, asi que recomendamos uno de los otros métodos.
 
-Recomendamos el método 1 para la mayoría de usuarios. Los APKs instalados usando método 1 o 2 son compatibles el uno con el otro, pero no con las instalaciones usando método 3. Esta es debida a la misma clave digital (la nuestra), siendo utilizado en los métodos 1 y 2, pero una clave digital diferente (la de F-Droid) siendo utilizado en el método 3. Construir un APK de depuración usando método 4 excluye una clave enteramente. Firmando con claves  digitales ayuda a asegurar de que un
-usuario no esté engañado para instalar una actualización maliciosa a una app. 
+ 1. Agregando nuestro repositorio personalizado a F-Droid e instalarlo desde allí. Las instrucciones están [aquí](https://newpipe.net/FAQ/tutorials/install-add-fdroid-repo/).
+ 2. Descargando el archivo APK de [aquí](https://github.com/TeamNewPipe/NewPipe/releases) y posteriormente instalarlo.
+ 3. Usando el repositorio oficial de F-Droid. Este es el método más lento para obtener actualizaciones, ya que F-Droid debe reconocer los cambios, construir el APK aparte, firmarlo con una clave, y finalmente publicar la actualización.
+ 4. Construyendo la app usted mismo. Este es el modo más rápido para obtener nuevas características en su dispositivo, pero es mucho más complicado, así que recomendamos uno de los otros métodos.
 
-Mientras tanto, si quiere cambiar los fuentes por alguna razón (por ejemplo, la funcionalidad del nucleo de NewPipe se rompe y F-Droid aun no tiene la actualización), recomendamos el siguiente procedimiento:
-1. Repaldear sus datos a través de Ajustes > Contenido > Exporta base de datos para guardar su historia, subscripciones, y listas de reproducción
-2. Desinstalar NewPipe
-3. Descargar el APK del nuevo fuente e instalarlo.
-4. Importar los datos del paso 1 a través de Ajustes > Contenido > Importa base de datos.
+Recomendamos el método 1 para la mayoría de usuarios. Los APKs instalados usando método 1 y 2 son compatibles entre sí, pero no lo son con los instalados usando el método 3. Esto es debido a la clave de firmado, ya que los métodos 1 y 2 usan la misma clave (la nuestra), pero el método 3 usa una clave diferente (la de F-Droid). El método 4 excluye totalmente una clave de firmado. Las claves de firmado aseguran que el usuario no esté siendo engañado para instalar/actualizar una APK maliciosa. 
+
+Además, si quiere cambiar el método de instalación por alguna razón (por ejemplo: la funcionalidad del núcleo de NewPipe se rompe o F-Droid aún no publica la actualización), recomendamos el siguiente procedimiento:
+1. Respalde su información a través de Ajustes > Contenido > Exportar base de datos; esto guardará su historial (videos vistos y búsquedas), suscripciones, listas de reproducción y ajustes.
+2. Desinstale NewPipe.
+3. Descargue el APK con un método distinto e instálelo.
+4. Importe la información (la base de datos extraída del paso 1) a través de Ajustes > Contenido > Importar base de datos. Tenga en cuenta que esta opción superpondrá su historial actual (tanto de vídeos como de búsquedas), sus listas de reproducción y (opcionalmente) sus configuraciones.

  4. Atualização via F-droid. Este é o método mais lento para obter atualizações, pois o F-Droid deve reconhecer alterações, construir o próprio APK, assiná-lo e, em seguida, enviar a atualização para os usuários.
 
 Recomendamos o método 2 para a maioria dos usuários. Os APKs instalados usando o método 2 ou 3 são compatíveis entre si, mas não com aqueles instalados usando o método 4. Isso se deve à mesma chave de assinatura (nossa) sendo usada para 2 e 3, mas uma chave de assinatura diferente (F-Droid's) está sendo usada para 4. Construir um APK depuração usando o método 1 exclui totalmente uma chave. Assinar chaves ajudam a garantir que um usuário não seja enganado para instalar uma atualização maliciosa em um aplicativo.
