Add variables to client script input

This really helped me, and this will help people out immensely (especially if they're trying to do their own thing in angular).

I think it's good to add these but if you're going to add a table, add a talbe if not don't. I previewd the md page and it looks pretty bad w/the table stuff at the bottom. I think you just missed a blank line between 26, and 27 to make the table render. I'd recommend removing the table (comment or delete it) or completing the table.
