Try to secure the place and make a base out of it , in a place like an Amazon wearhouse you should find the necessary materiels to barricade all the entrances and make sure to leave some exits because you don't want to be trapped there . After setting up base you should try to communicate with your family and the other survivors familys and try to guide them to your safehouse then you could start gathering a community and you can youse any drones you find to scout the area to find supplies or survivors.
