-1. **Load `libvulkan.so.1`** via `NativeLibrary.Load()`
+1. **Load the platform Vulkan loader** via `NativeLibrary.Load()` (`vulkan-1.dll` on Windows, `libvulkan.so.1` on Linux)
 2. **`vkGetInstanceProcAddr`** — only directly-loaded function
 3. **Create instance** with SDL3 extensions + `VK_EXT_debug_utils` (if validation available)
 4. **Pick physical device** — prefer `DiscreteGpu`

+## Quick Start — Windows x64
+
+PowerShell scripts select the Windows native runtime assets explicitly; Bash is
+not required:
+
+```powershell
+# Build and restore Windows native dependencies
+dotnet restore .\CORTEX_ENGINE.sln -r win-x64
+dotnet build .\CORTEX_ENGINE.sln -c Debug -r win-x64 --no-restore
+
+# Run the engine
+.\scripts\run.ps1
+
+# Run a demo scene
+.\scripts\run.ps1 --scene shooter
+
+# Run with AI/MCP server
+.\scripts\start_mcp_engine.ps1 -Port 5000
+
+# Run tests
+dotnet test .\tests\Engine.Tests\Engine.Tests.csproj -c Debug -r win-x64
+```
+
+The project keeps Linux as the default RID on Linux hosts and selects `win-x64`
+automatically on Windows. Use `-r win-x64` when cross-publishing from another
+OS.
