Tutorial On Mapmywalk/Fitness Pal Sync

I am a long time myfitnesspal user and recently started using Mapmywalk while walking and
bike riding. I'm having a terrible time trying to sync the two apps. so that I can get the information
from my phone app. (Mapmywalk) onto my PC version of myfitnesspal.
I need some basic information on how to do this.
Any help would be appreciated.
