This repository is a Chinese-first, continuously maintained guide to building VPN software with the modular SingLink architecture. It covers client applications, control planes, protocol adapters, subscription outputs, node operations, key management, privacy, testing, and app-store delivery.
The starter code is educational and not a complete production VPN service. It documents public architectural boundaries without publishing SingLink production code, credentials, nodes, or customer data.
Start with the Chinese README, review the roadmap, or visit VPNDevelop.
