+### NookLink
+
+All NookLink commands may automatically request a web service token. This will involve the splatnet2statink and flapg APIs (or a custom server). This can be disabled by setting `--no-auto-update-session`, however this will cause commands to fail if there isn't a valid NookLink token.
