  The objective of the current paper is essentially twofold. Firstly, to make
clear the difference between two notions of rolling a Riemannian manifold over
another, using a language accessible to a wider audience, in particular to
readers with interest in applications. Secondly, we concentrate on rolling an
important class of Riemannian manifolds. In the first part of the paper, the
relation between intrinsic and extrinsic rollings is explained in detail, while
in the second part we address rollings of symmetric spaces on flat spaces and
complement the theoretical results with illustrative examples.
