-**Prepara tus juegos para iPhone desde una app de Mac. Sin comandos para el uso diario.**
+**Tus propios juegos, preparados para iPhone, iPad o Mac.**
+
+## Empieza aquí
+
+**Primero:** instala [Xcode](https://apps.apple.com/app/xcode/id497799835) completo desde App Store y ábrelo una vez. **Xcode también compila los juegos**; una interfaz ya compilada no elimina ese requisito.
+
+**Después:** pega este único comando en Terminal:
+
+```bash
+/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/nalancer08/nxnative-easy/main/install.sh)"
+```
+
+Descarga nxnative Easy, instala Homebrew y las herramientas que falten, **compila tu interfaz de Mac y la abre**. Sigue las solicitudes de contraseña o confirmación que aparezcan en Terminal. No usa una cuenta de desarrollador Apple.
+
+**¿Ya descargaste el repositorio?** Abre **START-HERE.command** en la carpeta principal con doble clic. Hace la misma preparación; no necesitas buscar scripts dentro de `scripts/`. Si macOS bloquea ese archivo, usa el comando de arriba.
+
+Cuando abra la app:
+
+1. Elige **iPhone / iPad** o **Mac**.
+2. Selecciona la **carpeta de tu juego** y la **carpeta de tus llaves**.
+3. Pulsa **Preparar juego**.
+
+**Las siguientes veces:** abre **nxnative Easy.app** en la carpeta **Aplicaciones de tu usuario**. La preparación conserva su propia copia del código; puedes borrar el ZIP y la carpeta que descargaste.
+
+**Mac:** crea una `.app` del juego; pulsa **Abrir juego**. No necesitas Sideloadly ni un iPhone. Las partidas quedan en `~/Library/Application Support/nxnative/<title ID>/`.
+
+**iPhone / iPad:** crea una IPA ligera sin firmar. Instálala con Sideloadly y copia los datos del juego como te indica la app.
+
+**Necesitas:** Mac con Apple silicon (M1 o posterior), macOS 26+ y Xcode 26+. El comando instala las otras herramientas. Los juegos y las llaves los aportas tú. La primera compilación puede tardar.

 - **Preparación local:** sin cuenta Apple, sin certificados de empresa y sin servicio que reciba tus archivos.

+Entregamos **código, una interfaz de preparación y herramientas de compilación**. El resultado es una app local para Mac o una IPA para iPhone/iPad sin firmar, que firmas e instalas con Sideloadly. No ofrecemos juegos, llaves, firma de Apple ni compatibilidad garantizada con cualquier juego.
 
 ## Idioma
 
 La app inicia en **English**. Cambia a **Español** con el selector de la esquina superior; la elección se guarda en este Mac. Cambia el idioma de la interfaz, no el del juego. Los detalles técnicos se muestran en su idioma original.
 
-## Abre la app y elige tu juego
+## ¿Qué pasa al pulsar Preparar juego?
 
-1. Abre **nxnative.app**.
-2. Elige la **Carpeta de tu juego**, selecciona tu **Carpeta de llaves** una vez y pulsa **Preparar juego**.
+La app prepara las herramientas y compila para el dispositivo que elegiste. **Mac** genera una app del juego con los botones **Abrir juego** y **Mostrar app**. **iPhone / iPad** genera una IPA ligera y muestra los pasos de Sideloadly y Finder al terminar. Tus archivos y salidas anteriores se conservan en la carpeta del juego.
 
-La app prepara las herramientas, compila y deja lista la **IPA ligera**. Verás el avance en la ventana. Al terminar aparecen los dos pasos para instalar. **Enviar a Sideloadly** abre allí la IPA preparada; si Sideloadly no está instalado, el botón ofrece descargarlo.
-
-**Una vez creada:** abre `nxnative.app`. Recuerda tu última carpeta y permite volver a mostrar la IPA ya preparada.
-
-**En otro Mac:** después de descargar este repositorio, abre [`scripts/Abrir-interfaz.command`](scripts/Abrir-interfaz.command) con doble clic. Crea y abre la app local. La primera vez necesitas Xcode completo y Homebrew instalados; si hacen falta tus llaves, te pedirá elegir la carpeta donde guardas tu propio `prod.keys`. Mantén cada juego fuera del repositorio, en una carpeta con su base y actualizaciones.
+La preparación conserva una copia separada del código y respeta los cambios locales. Para desarrollo sigue disponible [`scripts/Abrir-interfaz.command`](scripts/Abrir-interfaz.command).

-**Prepare your games for iPhone with a native Mac app. No commands for everyday use.**
+**Your own games, prepared for iPhone, iPad or Mac.**
+
+## Start here
+
+**First:** install full [Xcode](https://apps.apple.com/app/xcode/id497799835) from the Mac App Store and open it once. **Xcode compiles the games too**, so a prebuilt launcher cannot remove this requirement.
+
+**Then:** paste this single command into Terminal:
+
+```bash
+/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/nalancer08/nxnative-easy/main/install.sh)"
+```
+
+It downloads nxnative Easy, installs Homebrew and the missing build tools, **compiles your own Mac interface and opens it**. Follow any password or confirmation prompts in Terminal. No Apple developer account is used.
+
+**Already downloaded this repository?** Double-click **START-HERE.command** in its top-level folder. It performs the same setup; you do not need to find a script under `scripts/`. If macOS blocks that file, use the Terminal command above.
+
+When the app opens:
+
+1. Choose **iPhone / iPad** or **Mac**.
+2. Choose your own **game folder** and **keys folder**.
+3. Click **Prepare game**.
+
+**After setup:** open **nxnative Easy.app** in your home **Applications** folder. The setup keeps its source checkout separately, so you can delete the downloaded ZIP and folder.
+
+**Mac:** creates a game `.app`; click **Open game**. No Sideloadly or iPhone needed. Saves stay in `~/Library/Application Support/nxnative/<title ID>/`.
+
+**iPhone / iPad:** creates an unsigned lightweight IPA; install it with Sideloadly, then copy the game data as shown in the app.
+
+**Required:** an Apple silicon Mac (M1 or newer), macOS 26+ and Xcode 26+. The command installs the other tools. You must provide your own games and keys. Compilation can take time, especially for the first game.

 - **Your own keys:** explicitly select the external folder containing your `prod.keys`. No games or keys are included, downloaded or distributed.
 - **Local preparation:** no Apple account or company certificate is used to build the desktop app.

+We provide **source code, a preparation interface and build tools**. The output is a local Mac game app, or an unsigned iPhone/iPad IPA that you sign and install yourself with Sideloadly. Games, console keys, Apple signing and universal game compatibility are not provided.
 
 ## Language
 
 The app starts in **English**. Choose **Español** using the selector at the top; your selection is remembered on this Mac. This changes the interface language, not the game's language. Build diagnostics keep their original language.
 
-## Open the app and choose your game
+## What happens after Prepare game?
 
-1. Open **nxnative.app**.
-2. Choose **Your game folder**, select your **Keys folder** once, then click **Prepare game**.
+The app prepares the tools and builds for your chosen device. **Mac** produces a game app with **Open game** and **Show app** buttons. **iPhone / iPad** produces a lightweight IPA and shows the Sideloadly and Finder steps when ready. Your own files and previous outputs stay in the game folder.
 
-The app prepares the tools, builds the game app and creates a **lightweight IPA**. Progress stays in the window. When finished, the app shows the two installation steps. **Send to Sideloadly** opens the prepared IPA in Sideloadly; if it is not installed, the button offers its download.
-
-**First-time setup:** download or clone this repository, then double-click the local [`scripts/Abrir-interfaz.command`](scripts/Abrir-interfaz.command) file in Finder. It creates and opens the Mac app. Full Xcode and Homebrew must already be installed. Select the folder containing your own `prod.keys` when asked. Keep one game per folder, with the base game and its updates, outside this source checkout.
-
-**Already set up:** open the existing `nxnative.app`. It remembers your last game folder and can reveal a previously prepared IPA.
+Setup keeps a separate source checkout and preserves local edits. Developers can still use [`scripts/Abrir-interfaz.command`](scripts/Abrir-interfaz.command).

 The normal build workflow still requires Xcode/Homebrew first and installs other
 missing dependencies. No Apple identity is selected by the desktop compiler.
+
+## One-command setup and destination selection
+
+`install.sh` installs missing Homebrew/build tools, prepares an isolated Python
+runtime, compiles the desktop app locally and opens it. Full Xcode must already be
+installed and opened once; the script checks this before downloading anything.
+The install uses an independent source checkout and never resets local changes.
+`--check` reports prerequisite status without installations or network access.
+
+Users must explicitly choose iPhone/iPad or Mac before preparing a game. The iOS
+route preserves the lightweight IPA workflow and `nxnative-ios.json`. The Mac route
+uses the upstream `--platform mac-app` packer with explicit ad-hoc signing, a unique
+output path per build and a separate `nxnative-mac.json` output record. It uses the
+upstream per-title save location without replacing iOS state. Apple silicon is
+required. Successful packaging is not a new claim of gameplay verification.
