+WebServer
+=========
+Provides a Web Server simulation by extending the base Service class.
+
+Key capabilities
+^^^^^^^^^^^^^^^^
+
+- Simulates a web server with the capability to also request data from a database
+- Allows the emulation of HTTP requests between client (e.g. a web browser) and server
+    - GET request sends a get all users request to the database server and returns an HTTP 200 status if the database is responsive
+- Leverages the Service base class for install/uninstall, status tracking, etc.
+
+Usage
+^^^^^
+- Install on a Node via the ``SoftwareManager`` to start the `WebServer`.
+- Service runs on HTTP port 80 by default. (TODO: HTTPS)
+
+Implementation
+^^^^^^^^^^^^^^
+
+- HTTP request uses a ``HttpRequestPacket`` object
+- HTTP response uses a ``HttpResponsePacket`` object
+- Extends Service class for integration with ``SoftwareManager``.
