The open_side.sh is a script to open secondary screen. But everyone’s computer hardware is different. Thus, you could adjust the interface name of the display in the script. Please refer to the 'xrandr' command. I recommend you to read i3wm 用户说明书. And the wallpic.sh use the package of archlinux-wallpaper. But you could change the wallpaper path.

In addition, you can change the path of the script as you want, but please you mind to change the path in the configuration file.
