MFP also links with other fitness and tracking apps, so I have it linked to my FitBit. It automatically uploads my steps in my daily diary and if I have more movement than MFP accounted for in my calorie goal, it adds more calories.
I took a bunch of screenshots of what I use and view on a daily basis and added my notes to each. I hope this is helpful!
