System Support

Operating Systems: Linux (glibc/musl), macOS
Architectures: x86_64, ARM64, ARM v7, ARM v6, i386

Auto-Detection Features

System Detection: Automatically identifies operating system, architecture and libc type
Tool Detection: Automatically selects curl or wget download tool
Network Optimization: Automatically tests and selects the best download mirror (github.com → China mirror sites)
Manual Override: Use --proxy to specify a proxy domain/mirror prefix, which takes precedence over auto-detection

Troubleshooting

Permission Issues: Use sudo or install to user directory
Network Issues: Script automatically uses mirror sites (hub.gitmirror.com, proxy.gitwarp.com, etc.)
Unsupported Architecture: Check releases page for supported architectures
Proxy Environment: The script respects system proxy settings (HTTP_PROXY/HTTPS_PROXY); you can also use --proxy https://hub.gitmirror.com/ to specify a GitHub mirror prefix (overrides auto-detection)
