-# Vyla Home
+# Vyla Home Engine
 
-Vyla Home is a desktop version of Vyla, built to run entirely on your own computer instead of on [vyla.cc](https://vyla.cc).
+A high-performance, locally executed environment for the Vyla media ecosystem. Built on the Tauri v2 framework, Vyla Home acts as a secure native bridge between local microservices and a lightweight WebView2 rendering engine.
 
-## Why this exists
+## Architecture & Security
 
-Running Vyla as a hosted website has been a constant source of stress. Hosting providers routinely block or throttle traffic coming from data centers, which is exactly where most affordable hosting lives. Every workaround for that involves paid infrastructure — residential proxies, dedicated IPs, premium tiers — that isn't realistic to keep funding long-term.
+Vyla Home is designed around complete local isolation to maximize speed, privacy, and reliability:
 
-On top of that, there's the standing fear that comes with depending on someone else's infrastructure: a provider changes their policy, a server gets flagged, an account gets suspended, and everything just stops working with no warning. That uncertainty has genuinely cost some sleep. Waking up wondering if the whole project got wiped overnight isn't a sustainable way to build something.
+- **Zero External Reverse-Proxies**: All routing, API endpoints, and authentication middleware run strictly on local loopback interfaces (`127.0.0.1`), eliminating ISP throttling and data-center IP bans.
+- **Native Memory Management**: Background Node.js lifecycle states are managed directly via OS-level memory handles (bypassing slow shell wrappers) for instant startup and teardown.
+- **Cryptographic Obfuscation**: Client configurations and credentials are secured on-disk via hardware-derived AES-256-GCM encryption.
+- **Automated Integrity Patching**: Payloads are dynamically verified using SHA-256 checksums and patched in-memory via C-level buffer scans.
 
-Vyla Home is the answer to that. Instead of fighting hosting providers forever, the app runs locally on your own machine. No data center traffic to block. No hosting bills. No one else's finger on the switch.
+## Build Requirements
 
-## What it actually is
+- [Rust](https://www.rust-lang.org/) (Latest Stable)
+- [Node.js](https://nodejs.org/) (v20+ LTS)
+- Tauri CLI (`npm install -g @tauri-apps/cli`)
 
-Vyla Home packages up the same player, streaming, and live-sports features as the website, wrapped in a small desktop app. When you open it:
+## Compilation
 
-- It grabs the latest version automatically
-- It starts everything up locally on your computer
-- The interface opens in its own window, just like the website did
+The build pipeline has been optimized with Fat LTO and aggressive panic aborts to generate the smallest possible binary footprint.
 
-Everything runs for you, on your machine, for your own personal use.
+```bash
+npm install
 
-## What this is not
+npm run build:payload
 
-This isn't a public service or a way to redistribute anything. It's a personal media player for personal use — think of it as watching things you already have access to, through your own local player, instead of a public streaming platform. Nothing here is intended to be shared, resold, or run as a service for other people.
-
-## Status
-
-Might not be actively worked on. Expect various bugs — this is a solo project built to solve a real problem, not a polished commercial product.
+npm run build
