This is a pretty early draft, but I'd be interested in any thoughts.

np: do you wanna put the troubleshooting section a bit further back in the list?

I think we went back and forth (literally on the list too :p)

thinking more, technically op-support can be under partitioner.

So thinking out loud,

partitioner, quantizer (two entry point, separate pages)

tutorials (curious why it is not here?)

internals (can also house reference material facts which can't be part of parishioner or quantizer)

guide/troubleshooting/gotcha/faq (one page with a title reflecting it is for all these :p)
