Hi!
To meet some of my needs, I modified (and added) in the past some helpers on my servers hosting Ghost.
But I would like to go further and also adapt the administrative part of Ghost, in particular the database, while keeping compatibility with Ghost updates.
So I was wondering if there are any guides or people who have done this kind of editing and explained how they did it through blog posts.
Also, Iād like to subscribe to authors who blog about Ghost itself! 
For those interested, myself I sometimes blog on Ghost and you can find my posts here: Ghost CMS - Benjamin Rancourt - Benjamin Rancourt.
Thanks!
