You can use manual/tutorials available on QTR web page. There is a lot of content, but curve creation, at least if you use original inks, is fairly simple:
1) print ink separation target for all of your channels (in fact black and grays would be enough at the beginning) for given % of ink limit (which you can estimate by printing the same for 100% first and then finding by CM the darkest black while it stops getting more black)
2) measure the darkest patch of each gray in relation to black (you can even do it with scanner, since no absolute values are needed, only relative) - with ColorMunki you use spot metering
3) put those values in the curve creation tool (for beginners by modification of some default paper curves included in QTR)
4) print 21 or 51 step wedge with those settings (e.g. CM 21 chevron-like tiff is available in QTR)
5) measure the values of the wedge - by spot or strip measuring (writing down L* values menually or by exporting the whole measured CM palletd to cxf and then importing to Excel using xlm import macro easy to find on the web)
6) put the values into linearisation tab, and that's all.
If you want to change tint of the print, you must experiment.
In my opinion, the most important is to know how QTR works, more than having step-by-step instruction for given spectro - QTR documentation is far from ideal and it leaves number of actions for aware user to experiment.
hope it helps
