isn't it, @yuvipanda ?! the only thing that you may see me fighting with is it doesn't work properly when you to add multiple people at once (and so you can get merge conflicts adding one by one). But i keep thinking this is a great way to remember to add people and then i can add after the fact them to our website, zenodo files etc as contributors!! otherwise it's so hard to keep track of all of the various contributions !
