+/*
+  ESP32 mDNS responder sample
+
+  This is an example of an HTTP server that is accessible
+  via http://esp32.local URL thanks to mDNS responder.
+
+  Instructions:
+  - Update WiFi SSID and password as necessary.
+  - Flash the sketch to the ESP32 board
+  - Install host software:
+    - For Linux, install Avahi (http://avahi.org/).
+    - For Windows, install Bonjour (http://www.apple.com/support/bonjour/).
+    - For Mac OSX and iOS support is built in through Bonjour already.
+  - Point your browser to http://esp32.local, you should see a response.
