+/**
+ * @example web_setup/example.cpp
+ *
+ * This is an example of using the web setup network API to
+ * configure the module network credentials remotely.
+ *
+ * It works as follows:
+ * 1. Instantiate the WiConnect Library
+ * 2. Initiate Communication with WiFi Module
+ * 3. Start WebSetup with specified parameters
+ * 4. Wait for web setup webpage to complete
+ * 5. That's it!
