To begin the story, you need to craft a Receiver, 3 Antennas and a Battery [how to craft and use the Receiver]. The moment you turn your receiver on, you’ll receive a note with coordinates (4 numbers), enter them and follow the blue square that appears on the receiver’s radar.
Every note and quest item will go in your journal, that way you can’t lose them even if you die. Your journal can be found on the right of your toolbar, key to open it can be changed in the settings.
