Omg, 40 steps. Also touchbar version has smaller battery, are you sure this guide for 2016 and function version would apply for 2017 one with a touchbar?

It won’t apply i’m Afraid but iFixit will have a guide if you search their site. Honestly if you can pay someone else or it’s within apples warranty (they will replace it for free if it’s within the first yearand has less than a thousand charge cycles and less than 80% capacity 3 years with apple care.) then pay someone else to do it the battery will be expensive anyway.
