Portable Generator Power A House Not Connected To The Grid?

How Can i connect a 5000W portable gas generator to power an entire house??? The home has been wired but is not connected to the grid no braker box, no meter or anything all the rooms were wired together. No major appliances are going to be used just 5 15watt bulbs, a 21in TV, a radio, hair dryer, cell phone charger, and a laptop. What would be the safest way to power this house using a 5000w generator????
