I am sorry if somebody don't understand it. This is the plug-in which has very common controls (unlike the VintageWarmer for instance) and doesn't require any extra knowledge other then when using another compressor. The main difference is in this case an expearience and expectations.
For instance no body excect true mastering engineers and some top mixing engineers would be Manley Vari-Mu because only those guys really know that this gear is worth its high price, they really understand what it does to the sound.
There is no way to describe practices for a compressor which is not tend to be a tool for begginers because without experiance it is really hard to expect and hear how it should really work.
Of course the idea to attach articles to manuals which would help in compression isn't a bad idea but it won't help you in any way to choose the MasterComp.
In other words it is possible to make an introduction on what the compressor is and what does every parameter but we cannot give guidelines how to get a good sound of it because its every setting can be good depending on individual situation.
But, hey, I just found an article on the net that you could read if it is really what you would expect:
