Theorem
Let $M$ be a smooth manifold.
Then $M$ admits a Riemannian metric.
This article, or a section of it, needs explaining. In particular: What does this "admit" mean? You can construct a metric from the Euclidean metric and the differentiable structure on $M$ OK, now I probably understood. The statement should be then more explicit like: there exists a Riemannian metric such that 1). .. 2). .. etc. Otherwise it is not clear what is to be proved. You can help $\mathsf{Pr} \infty \mathsf{fWiki}$ by explaining it. To discuss this page in more detail, feel free to use the talk page.
