How It Works

The installer performs three steps:

1. Toolchain Setup — Installs the required build toolchain if not already present
2. Neo CLI — Installs the Neo command-line interface
3. Verification — Confirms everything is working correctly

After installation, run neo new myproject to create your first project.

Architecture

The installer is built in Rust and uses the Determinate Nix Installer under the hood to set up the Nix package manager, then installs Neo CLI via nix profile install.

Source modules:

• detect.rs — Platform and existing installation detection
• install.rs — Nix and Neo CLI installation logic
• verify.rs — Post-install verification
• ui.rs — Terminal output and progress indicators
• error.rs — Error types and exit codes
