Follow the instructions at GetLofi.  You're basically providing power to the chip, cutting a trace on the PCB that previously supplied the CPU with a clock signal, and connecting the output of this chip to the CPU's clock input.

Do I really need a 0,1uF capacitor?

Probably not but you should use one.  When you go from +V to GND like this it's being used to help keep the supply voltage stable, which probably helps it keep the output frequency stable.

This adapter is slightly different than the LTC 1799 from Getlofi (http://getlofi.com/gameboy-dmg-01-pitch-modification/)

How do I connect this thing? Do I really need a 0,1uF capacitor?
