Sitecore 8.1 How to extend Experience Profile

Question

I'm currently tracking the visitors of the website. I've added a new facet and the information is being added to MongoDB. I thought that the experience profile would pick this new info but apparently not. I tried to find a way of showing this facet but what I've found so far seems way too complex. https://jonathanrobbins.co.uk/2016/03/15/extending-sitecore-experience-profile-experienceprofilecontactviews/ Anyone found any good documentation on how to do this? Thanks
