[Plugin: Advertising Manager] No direction whatsoever provided on using this!

There is absolutely no direction that I can find on exactly how to use this plugin. I moved the widgit to my sidebar and the only directions are to drop in the name and save it – from where?! What name? Where are the settings to configure the ad? I’ve worked really hard bringing my blog along to where I’m happy with the look and traffic is finally growing so I’m not about to screw it up trying to figure out how to use this so I’m unloading it now. I feel no shame in admitting I’m still learning – but I am at a loss to understand how this plugin got the high rating it did – especially after reviewing the comments on this page.
