 - `./scripts/build-linux.sh` - Linux (Run only after build-appimage.sh)
+- `.\scripts\build-windows.ps1` - Windows

+#### Prerequisites
+##### Windows

+Before building on Windows, install the following:
+
+* **[Visual Studio Build Tools 2026](https://visualstudio.microsoft.com/downloads/#visual-studio-2022-tools)** (or newer) with the **"Desktop development with C++"** workload — provides MSVC compiler and Windows SDK.
+* **[CMake](https://cmake.org/download/)**
+* **[Rust](https://rustup.rs)** (`rustup`) 
+* **[OpenSSL](https://slproweb.com/products/Win32OpenSSL.html)**
+* **[Flutter SDK](https://docs.flutter.dev/get-started/install/windows)**
+> [!IMPORTANT]
+> You must run build as admin and without VPN in Russia you can't build because one is libs can't be download
