One manual, written by building a cluster and then tested by wiping the machines and building another one from nothing following only what it says.
122 pages. Thirty eight chapters and five appendices: the ideas, installing, adding machines, every screen, the tunnel, sizing, security, and a troubleshooting chapter that names the failures rather than describing them in general.
It ships with the source, in docs/MySQL_Cluster.docx.
A shorter tour in the repository: what it does, how the parts fit together with diagrams, running one node, adding a node, retiring one, and what is deliberately not built.
