Hi rafikipress,
I’m the developer. Take a look at my blog post about the plugin: http://blog.paulnshapiro.com/new-google-plus-interactive/
If you look at the comments, I have been (I think) very good about helping people figure things out and troubleshoot.
Between this post and the readme.txt I was under the impression that would be sufficient documentation. If I am still wrong, let me know what you think is missing from either and I will surely update it or try to make things clearer.
Thanks for the feedback,
Paul
