I've started reading the little riak_core book but could not find a high-level presentation of what actually is riak_core, or what is riak_core responsible of. It might be a good added value to make a short introduction about what riak_core is and what it is not. In this context, the book could link to http://basho.com/posts/business/introducing-riak-core/ and http://basho.com/posts/technical/where-to-start-with-riak-core/ as "dive into" riak_core. Considering the situation of the documentation hosted on basho.com following the demise of basho, maybe it is even more interesting to take this documentation right into the book.
