It has been 2 days that the Steam Network released the Skyrim Patch1.4 for Download among a enormous amount of Mods you can install. The installation process is much easier compared to the Nexus Mod Manager, although it requires you to have purchased Skyrim using Steam.
Now browse all the Mods and to install, simple select the green subscribe button.
Log in to your game and that is it. You are good to go.
