Using REW and rephase to generate amplitude and time domain corrections

[RAzZin]

Guys, could you please explain what to do starting from the end of p. 3 of the guide:

 

"The excess phase, which has been generated, can now be exported as .txt to rePhase,
where it will serve to make the time domain correction."

 

I load the excess phase (I received it as an almost flat line with a small dip on 200hz) to rePhase.. then what? What do I have to do in p.4? I'm completely lost there, could you please tell me next steps, in what buttons to press manner?
