  $(".book-header,.book-summary,.navigation,.book-progress").remove();
  $(".book.with-summary .book-body").css('left', '0px');

--pretty="..." defines the format of the output.
%h is the abbreviated hash of the commit
%d are any decorations on that commit (e.g. branch heads or tags)
%ad is the author date
%s is the comment
%an is the author name
--graph informs git to display the commit tree in an ASCII graph layout
--date=short keeps the date format nice and short
