Write a "definitive usage guide"
A lot of issues have been posted about similar topics, such as SSH usage, devices not responding to pings, etc. My initial hope was that the documentation available in the README, along with other sources of help would suffice. It has become apparent, however, that what is lacking is a guide / step-by-step how to configure the plugin in common environments and more importantly, how to effectively troubleshoot the setup.

There's a lot of helpful information hidden in issues, discussions and as a wiki post. By combining all of this information and by adding to it, we should be able to provide a meaningful document for using the plugin.
