  Manifold calculus of functors has in recent years been successfully used in
the study of the topology of various spaces of embeddings of one manifold in
another. Given a space of embeddings, the theory produces a Taylor tower whose
purpose is to approximate this space in a suitable sense. Central to the story
are deep theorems about the convergence of this tower. We provide an exposition
of the convergence results in the special case of embeddings into $\mathbb
R^n$, which has been the case of primary interest in applications. We try to
use as little machinery as possible and give several improvements and
restatements of existing arguments used in the proofs of the main results.
