What is NyanBox ? Well that is Openbox, and what is that ? :

Openbox is a lightweight, powerful, and highly configurable stacking window manager with extensive standards support. It may be built upon and run independently as the basis of a unique desktop environment, or within other integrated desktop environments such as KDE and Xfce, as an alternative to the window managers they provide. The LXDE desktop environment is itself built around Openbox.
A comprehensive list of features are documented at the official Openbox website. This article pertains to specifically installing Openbox under Arch Linux.
On this article I will show my Openbox config.

Installation :

$ sudo pacman -S openbox tint2 obmenu-generator compton nitrogen lxappearance-obconf volumeicon lxsession

Copy default configuration on /etc/xdg/openbox to ~/.config

$ cp -R /etc/xdg/openbox ~/.config/

Edit autostart configuration :

$ nano ~/.config/openbox/autostart

My autostart config :

(sleep 1s && tint2) &
nitrogen --restore &
setxkbmap us &
(sleep 3 && nm-applet) &
(sleep 3 && volumeicon) &
xfce4-powermanager &
/usr/bin/lxpolkit &
urxvtd &
compton &

Edit menu.xml configuration for obmenu-generator :

$ nano ~/.config/openbox/menu.xml

My menu.xml config :

<?xml version="1.0" encoding="utf-8"?>
<openbox_menu xmlns="http://openbox.org/"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://openbox.org/">
    <menu id="root-menu" label="obmenu-generator" execute="/usr/bin/obmenu-generator" />
</openbox_menu>

Copy default configuration obmenu-generator on /etc/xdg/obmenu-generator to ~/.config

$ cp -R /etc/xdg/obmenu-generator ~/.config/

Edit schema.pl configuration :

$ nano ~/.config/obmenu-generator/schema.pl

My schema.pl config :

require '~/.config/obmenu-generator/config.pl';

our $SCHEMA = [
