+# Tower Layer
+
+Decorates a `Service`, transforming either the request or the response.
+
+## Overview
+
+Often, many of the pieces needed for writing network applications can be
+reused across multiple services. The `Layer` trait can be used to write
+reusable components that can be applied to very different kinds of services;
+for example, it can be applied to services operating on different protocols,
+and to both the client and server side of a network transaction.
