Thanks for your response @effigies.
Okay, yes, I also though about the README.
In my case this will become quite long though (more minor and major issues during scanning than we’d have liked 
), that’s why I thought a separate file dedicated to all study-relevant notes could be useful.
Along those lines, wouldn’t it be possible to add a /docs folder than contain all sorts of extra information relevant for the BIDS dataset? Curious about your opinion. Thanks!
