Existing ButcherMultiStageScheme for casual use

Could anyone please provide an example of using ButcherMultiStageScheme for usual time stepping?

I am thinking about a problem in form

M \frac{d x}{d t} = K(t) x

or subject to time-dependent boundary conditions. Here x is a state function, defined in some domain, and K is a fem - discretisation matrix (or an differential operator, in continuous form).

Thank you!
