To install the plugin unzip the archive and upload the "socializer" folder inside the plugins folder of your blog, then activate Socializer! and configure it.
Content, Shortcode, Simple and Floating Widget bars are all configured from the Socializer! page at the Settings section of your blog, and can be styled there further, or even using your main style sheet.
For WordPress multisite MS / MU installations you can activate the Socializer! globally, for all the sites of your network, or just install it on the network admin, leave it deactivated there, and activate it on (any number of) individual blogs.
