-1. Server settings are located in `./settings.json`, you need to change serverAddress in order to deploy
+1. Server settings are located in `./pb-data/settings.json`, you need to change serverAddress after frist launch in order to deploy
 
-2. When catches SIGUSR1, server will save a board with name read from settings file. SIGINT (CTRL + C) does the same but exit server when board is saved **KILL WITH SIGTERM WILL NOT SAVE THE BOARD!**
