What details do you expect? It's a PSD to Sketch converter, what else do you expect it to say? He could have filled it with a "gorgeous", "unique", "innovative" marketing keywords but it would still be a PSD To Sketch converter.

I just tried converting a really big photoshop file and it worked pretty good, why don't you try it before making comments on it's functionality?
There are lots of details that could be helpful. What kind of limitations are there? What does it convert? Is anything discarded in the conversion process? What does it do with items where there isn't a 1:1 conversion? What does it do to features that aren't available in Sketch? You know... the things that are included in the description that OP provided in response to my comment and that he updated the main thread with... There is a lot of technical info that would be helpful. I didn't have a .PSD file handy to test so I was asking to try and be informative and helpful.
The converter actually works pretty well even with large and complex designs. You should really try it out. There are still some features that we're working on.
