I want to have a better "working knowledge" of stacks. However every time that I approach the topic, I finish hitting a wall of technical details. They are essential, but I don't need them for now.

So, I am wondering where I can find a "naive" description of stacks. Something better than the story of the functor of points at the level of the book Geometry of schemes, but without all the technical weight of the Stack project or Martin Olsson's book.

I am ok if there are small white lies here and there; and if the generality is not as high as possible.

Thanks!
