 # ``DoxyLibrary``
 
-<!--@START_MENU_TOKEN@-->Summary<!--@END_MENU_TOKEN@-->
+A library that provides the **Doxy** service builder to the `DoxyApp` executable target.
 
 ## Overview
 
-<!--@START_MENU_TOKEN@-->Text<!--@END_MENU_TOKEN@-->
+The library, in a nutshell, provides a public builder that creates a fully configured [Hummingbird](https://hummingbird.codes) 
+application that is ready-to-use by the `DoxyApp` executable target.
+
+In addition, all the business logic required by the `DocC` archives controller that provides the necessary resources, 
+and the `DocC` middleware that proxies the contents of documentation archives in the local machine is being implemented 
+in this target, including all its relevant protocols and types. Plus, the unit tests for every type implemented in this
+target are being written in the `DoxyTests` target.
