## Platform-Specific Installation and Compatibility

Sayso offers platform-specific installation options for macOS, Windows, and Linux. On macOS, it requires version 14 or later with Apple Silicon and can be installed via `brew install --cask watzon/tap/sayso`. For Windows, it supports version 10 (1809 or later) and 11 on 64-bit Intel or AMD processors. On Linux, it works on Debian 12 or later, Ubuntu 22.04 or later, and other distributions with glibc 2.35 or later. Linux users can install via Flatpak, AUR, or Nix flake, depending on their system. Linux compatibility includes X11 and Wayland, though it works by app only and not on GNOME or KDE with Wayland. Installation files are named `sayso--linux-`, with being `x86_64` or `aarch64`. API keys are stored in the Keychain (macOS), Windows Credential Manager, or Linux Secret Service keyring under `dev.sayso.Sayso`.

## Verification and Security of Downloads

Verification and security of Sayso downloads are emphasized through cryptographic hash checks and secure storage of API keys. For macOS users, the `shasum` command can be used to verify the integrity of the `.dmg` file by comparing it with the provided `.sha256` file. On Windows, users can use the `Get-FileHash` PowerShell command to confirm the hash of the `.exe` installer. If the installer is not signed, Windows SmartScreen will prompt the user before execution. API keys are stored securely in the macOS Keychain, Windows Credential Manager, or Linux Secret Service keyring, ensuring they are not exposed in plain text. Sayso is funded by voluntary contributions from users, with the download page at justsayso.app allowing users to specify a payment amount, including $0\. However, if Sayso is obtained from GitHub—via a release file, Nix flake, or source build—no payment prompt is shown. For building from source, users can run `git clone https://github.com/watzon/sayso.git` and use `SAYSO_SIGN_IDENTITY=- scripts/bundle.sh` to create an ad hoc signature without requiring an Apple developer account.

## Development and Build Requirements

The development and build requirements for Sayso involve several key components. On Windows, users must install the Visual Studio 2022 Build Tools with the 'Desktop development with C++' workload and a Windows SDK, along with CMake, LLVM (for libclang), and Rust 1.98.1\. The LIBCLANG\_PATH environment variable should be set if LLVM is not on the system PATH. To build the Windows executable, the command `powershell -ExecutionPolicy Bypass -File scripts\bundle-windows.ps1` can be used, which generates `build\windows\Sayso\Sayso.exe`. Adding the `-Installer` flag also creates an installer in the `dist\` directory.

For Linux, the `scripts/linux-deps.sh` script installs required packages (Debian and Ubuntu names) and Rust 1.98.1\. The `scripts/bundle-linux.sh` script then generates a tarball at `build/sayso--linux-.tar.gz`. To create .deb, .rpm, AppImage, and Flatpak packages from the tarball, run `scripts/package-linux.sh build/sayso--linux-.tar.gz`. API keys are stored in the Keychain (macOS), Windows Credential Manager, or Linux Secret Service keyring under `dev.sayso.Sayso`.
