+  Emberwild dedicated server as a launchd agent (macOS): starts when you log
+  in, and restarts if it stops.
+
+  1. Edit the two paths below (the game folder, and your user name in the log
+     path) if yours differ.
+  2. Copy it:   cp server/com.emberwild.server.plist ~/Library/LaunchAgents/
+  3. Start it:  launchctl load -w ~/Library/LaunchAgents/com.emberwild.server.plist
+     Stop it:   launchctl unload ~/Library/LaunchAgents/com.emberwild.server.plist
+     Log:       tail -f ~/Library/Logs/emberwild-server.log
+
+  server.json and the world are in
+  ~/Library/Application Support/Godot/app_userdata/Emberwild/server/
+  For admin commands, join the game and use chat (/help), or edit server.json
+  and stop/start it. (For a console, run server/run_server.sh in Terminal
+  instead.)
