I have two questions:

1. Is there any way to view a .docx file on Github? We have uploaded all of our assignments onto Github, but there is no way we can view it within the browser. It would be nice if we could view those .docx files in the browser without downloading the file.

2. How can I use git diff on the .docx file format? I tried to use catdoc but it didn't work for me. I think I have used git diff on Windows for the .doc format before, but it's not working for me on Mac.

Thanks a lot.
