  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.
