Sunrise Time-Lapse Help

[GingerGarden]

Hello everyone,
I am very new to ML, but I am learning quickly. I am using a Canon 60D and I am trying to set up a sunrise time-lapse and I am confused on some of the instructions pertaining to bulb-ramping.
The question that I have is about the first step in "quick start for automatic ramping" in the user guide. The first step is:

"Take a picture of your scene. You will use it to say: I want my timelapse to be exposed like this picture."

Does that mean take a picture while it is dark, or should I take a picture when the sun is up and use that as my reference picture?

Also, if there is a tutorial out there on how to use bulb ramping, let me know.
Thank you for your time!
