  We present some results on (co)limits of diagrams in $\infty$-categories, as
well as those in $(n, 1)$-categories. In particular, we deduce a way to reshape
colimit diagrams into simplicial ones, and a characterisations of
$n$-cofinality for functor between $\infty$-categories. Some basics on
$n$-siftedness are also briefly treated.
