vmCalculation

[nordmograph]

Hello

I need to code, for a client, a VM plugin to perform operations after an order is confirmed, whatever the payment and shipment methods  are.
As the documentation for plugins dev is not ready yet, and no vmcalculation plugin example is available, I'm asking here:

Should I code a  vmCalculation plugin?
And use the plgVmConfirmedOrder function?
Any tip welcome! Thanks in advance.
