In this short review main issues related to the non-Abelian Stokes theorem
have been addressed. The two principal approaches to the non-Abelian Stokes
theorem, operator and two variants (coherent-state and holomorphic) of the
path-integral one, have been formulated in their simplest possible forms. A
recent generalization for a knotted loop as well as a suggestion concerning
higher-degree forms have been also included. Non-perturbative applications of
the non-Abelian Stokes theorem, to (semi-)topological gauge theories, have been
presented.
