+# 🦀 Rust Development Environment Setup (Windows, Offline)
+
+This guide walks through setting up a complete **Rust development environment** on a **Windows workstation** that does **not have internet access**.
+
+## 📦 Overview
+
+You will prepare the following components **on an internet-connected machine**, then **transfer them via USB drive** to the disconnected workstation:
+
+- Rust toolchain (stable)
+- Cargo packages (pre-downloaded)
+- VSCode + Rust extension (offline VSIX)
+- Build tools (C++ compiler)
+- Optional: `rust-analyzer`, documentation
+
+---
+
+## ✅ Prerequisites
+
+### 🖥️ On Target Workstation (Disconnected)
+
+- Windows 10 or 11
+- Administrator privileges (optional but helpful)
+- USB port for transfer
+
+### 💻 On Source Machine (Internet Connected)
+
+- A separate Windows/Linux/Mac machine
+- Internet access
+- USB drive with at least 10 GB free
+
+---
+
+## 🔁 Step 1: Prepare Rust Toolchain
+
+### On Connected Machine:
+
+1. Download the Windows Rust installer:
+
+```bash
+https://static.rust-lang.org/dist/rust-1.77.2-x86_64-pc-windows-msvc.msi
+
+```
+> Replace version with latest stable, if needed.  
+
+2. Download associated `cargo`, `rustc`, and `rust-docs` tarballs:  
+```bash
+https://static.rust-lang.org/dist/cargo-1.77.2-x86_64-pc-windows-msvc.tar.gz
+https://static.rust-lang.org/dist/rustc-1.77.2-x86_64-pc-windows-msvc.tar.gz
+https://static.rust-lang.org/dist/rust-docs-1.77.2-x86_64-pc-windows-msvc.tar.gz
+
+```
+
+3. Download `rustup-init.exe` **if you want to use rustup offline:**  
+```bash
+https://static.rust-lang.org/rustup/dist/x86_64-pc-windows-msvc/rustup-init.exe
+
+```
+
+4. Transfer all files to USB.  
+
+---
+
+## 🧰 Step 2: Install Rust Offline  
+
+**On Target Workstation:**
+
+1. Run the MSI installer:  
+```powershell
+rust-1.77.2-x86_64-pc-windows-msvc.msi
+
+```
+> You can also run `rustup-init.exe` with the following:
+
+```powershell
+.\rustup-init.exe --default-toolchain 1.77.2 --no-update-default
+
+```
+
+2. Confirm installation:
+
+```powershell
+rustc --version
+cargo --version
+
+```
+---
+
+## 🧱 Step 3: Install C++ Build Tools (MSVC)  
+
+1. On internet-connected machine, download:  
+
+* **Build Tools for Visual Studio 2022:**  
+```powershell
+https://aka.ms/vs/17/release/vs_BuildTools.exe
+
+```
+
+2. On the connected machine, run:  
+```powershell
+.\vs_BuildTools.exe --layout .\offline_vs_buildtools --lang en-US --add Microsoft.VisualStudio.Component.VC.Tools.x86.x64
+
+```
+> This creates an **offline installer** directory.  
+
+3. Transfer `offline_vs_buildtools` folder to target.
+
+4. On the disconnected workstation:  
+
+```powershell
+.\offline_vs_buildtools\vs_BuildTools.exe --noweb --quiet --wait
+
+```
+---
+
+## 🧩 Step 4: Set Up VSCode Offline
