        first_line = "Slug: " + slug + "\n"

        # first read existing file in and save lines

        temp = f_old.read()
        f_old.close

        # then write the lines back out to the same file, prepending slug line
        f_new = open(current_file, 'w')
        f_new.write(first_line)
        f_new.write(temp)
        f_new.close
