Tailscale

This is a solid reference for running Tailscale in production. It covers the practical stuff you'll actually need: setting up subnet routers and exit nodes, configuring ACLs with the newer grants syntax, enabling Tailscale SSH, and exposing services with Serve and Funnel. The included scripts automate common setup tasks, and the reference docs go deep on access control patterns, API automation, and troubleshooting connectivity issues. Most useful when you're moving past a basic tailnet and need to handle team-based access controls, integrate multiple networks, or lock down a production deployment. The ACL examples alone will save you from re-reading the docs every time you need to grant SSH access.
