Dear wpNoob 2012,
First make sure your webserver is running WordPress 3.6 or higher.
Make sure jquery is loaded! Very important
Install the plugin via ftp / web installer ( I assume you have done that )
When the plugin is installed, search for this icon:
View post on imgur.com
Click on it, and you will see options to add logo’s.
View post on imgur.com
In the menu, you can view all your logo’s, add new logo’s, generate a shortcode (which you need to insert in to a post, you can also preview your logo carousel here) Categories and Settings.
So the only thing you have to do is upload some logo’s (of the correct size, 190 x 46 as an example and generate a shortcode and put it in a post!
That’s all.
Mark
