Possible clarification on how to do minimization with Sella

[goxeq]

I was wondering, if you considered an inclusion of explicit instruction how to do minimization using Sella in the in README.md file. It took me quite a long time to realize, that the default settings are the TS search and not minimization. Even some small comment, like below, might prevent some confusion:

dyn = Sella(
    slab,
    order=1, # 1 corresponds 1st order saddle point search, use order=0 for minimization
    constraints=cons,
    trajectory='test_emt.traj',
)
