How to install Xfce on ArchLinux

I am seriously thinking of trying ArchLinux to Xfce (don't scare me debianites) to see how it behaves. If I can install it (today) then I will do a tutorial on how to configure it step by step.

But if you are already a user of Arch, I leave you the steps to install Xfce without dying in the attempt:

1- To install a basic Xfce, we just have to put in the console:
# pacman -S xfce4

Or if you want an installation in a more specific way:
# pacman -S xfwm4 xfce4-panel xfdesktop thunar xfce4-session xfce4-settings xfce4-appfinder xfce-utils xfconf

2- To install the plugins (goodies) de Xfce we simply run this command:
# pacman -S xfce4-goodies

3- If we want xfce4-mixer work with ALSA, we have to install the following packages:

# pacman -S gstreamer0.10-base-plugins

4- Finally for what Xfce work properly we have to install DBus.

# pacman -S dbus

5- What for Xfce it looks nice we must install the engines gtk:

# pacman -S gtk-engines gtk-engine-murrine gnome-themes-standard

Starting Xfce.

If we don't install any Session manager (Login Manager) like LigthDM or Slim, we started Xfce with the command:
# startxfce4

Or if we want we add it to the file ~ / .xinitrc.
#!/bin/sh

if [ -d /etc/X11/xinit/xinitrc.d ]; then
for f in /etc/X11/xinit/xinitrc.d/*; do
[ -x "$f" ] && . "$f"
done
unset f
fi

exec ck-launch-session startxfce4

And up to here everything must be "normal" .. More info here.
