The README is now a landing page: the idea (a mesh VPN with no server, joined with a network name and a secret), install and platform tables, exit nodes, and a short build section. Implementation detail stays in docs/. The flake builds tsng and the tray from source and ships a NixOS module (services.tsunagi). Dist install notes now show the real `join -n -s` syntax, and two links that pointed into the old README are redirected. Co-Authored-By: Claude <noreply@anthropic.com>

Done. Start the agent with:
|
|
|
|
sudo systemctl enable --now tsunagi
|
|
|
|
Control it with sudo (the CLI finds the service's socket automatically):
|
|
|
|
sudo tsng status
|
|
sudo tsng join -n <network-name> -s <tsn1…secret>
|
|
EOF

|
else
|
|
cat <<EOF
|
|
|
|
Installed the binary; no systemd found, so no service was set up. Either:
|
|
|
|
* run it as root: sudo ${PREFIX}/bin/tsng up
|
|
* or as your own user: sudo setcap cap_net_admin,cap_net_bind_service+p ${PREFIX}/bin/tsng
|
|
tsng up
|
|
(add yourself to the tsunagi group so the resolver works:
|
|
sudo usermod -aG tsunagi "\$USER")
|
|
* or without touching the OS: tsng up --no-tun
