Memcached, moxi, vBucketMap - I don't understand anything?

Question

memcached

I decided to implement a proxy for memcached in my project - moxi ( code.google.com/p/moxi )
In the config there is a "hell matrix" for setting up vBucket - I still could not find "accessible and understandable" documentation on this config item.
Please tell me, a normal dock or an understandable example for setting up moxi.
