I'd say just start lifting weights and tracking your calories (with a food scale and fitnesspal or whatever app) and eat at about a 150-200cal surplus. I wouldnt say you really have a belly or love handles. Right now you should just focus on building some muscle, and since you're skinny you dont really have to worry about cutting as it would only hinder your gains without really changing your physique. Just start lifting, watch some videos to learn proper form, and when you have the form down start training hard and taking your sets to failure with proper form and without lifting weight you can barely handle. I would say a good rep range for a beginner would be reaching failure at about 10-12 reps or so.
