We study the action of the mapping class group $\mathcal{M}(F)$
on the complex of curves of a non-orientable surface $F$.
Following the outline of [1] we obtain, using the result
of [4], a presentation for $\mathcal{M}(F)$ defined in terms
of the mapping class groups of the complementary surfaces
of collections of curves, provided that $F$ is not sporadic,
i.e. the complex of curves of $F$ is simply connected.
We also compute a finite presentation for the mapping class
group of each sporadic surface.
