+- Securing HTTPS Communication -
+The Hypertext Transfer Protocol (HTTP) is a widely used protocol for application
+such as home media to interact with web servers. The Hypertext Transfer Protocol
+Secure (HTTPS) is an extension to HTTP, adding secure element to the connection.
+HTTPS is encrypted with Transport Layer Security (TLS), which also requires server
+authentication. In addition to server authentication, mutual authentication
+authenticates the identity of both the server and the client.
+
+- Pre-configured HTTPS Example Projects -
+The examples contained in subdirectories from here demonstrate the concepts
+described above one at a time.  The first example demonstrates plain text
+HTTP (insecure) communication, the second example builds on the first to
+introduce weak server authentication, and the third example builds on the second to
+introduce strong mutual authentication.  Note:  It is our recommendation to always
+use strong mutual authentication in any Internet of Things (IoT) application.  The
+plain text project is only provided to validate HTTP communication can be
+established prior to introducing encryption and authentication, and to allow the
+HTTP packets to be observed using a network packet sniffer such as Wireshark for
+those who wish to do so.  The first two projects are in no way intended to be
+examples suitable for production use.
