I will finish my overview of the de Rham fundamental group by reviewing two explicit calculations: Deligne's completely concrete description of the unipotent fundamental group of the projective line minus three points in terms of the free nilpotent Lie algebra on two generators, and Chen's general calculation of the unipotent fundamental group of a manifold in terms of iterated integrals.
