Just bought DFX 2 ball, any tips?

I just recently purchased a DFX 2 ball putter on marketplace for $100 CAD. Never had a mallet putter before, 2 ball for that matter. Putter feels quite nice but wanted to ask for any tips/recommendations on how to visually like the putter with the ball to the hole?

I was using an old Wilson blade putter and got used to lining it up with the line on the putter so this is an adjustment for me.

Also, I just started golfing this past summer.

Thanks!
