-# Arduino Restful Client
-
-This example demonstrates how to use [Mongoose](https://www.cesanta.com/mongoose) to send HTTP commands from Arduino.
-
-Example sends free memory size and current board uptime, but it can be modified to send any user-specific data.
-
-At the moment this example supports [Arduino Mega 2560](http://arduino.cc/en/Main/ArduinoBoardMega2560) board (and compatible) with either W5100-based
-network shield (like [Arduino Ethernet Shield](http://arduino.cc/en/Main/ArduinoEthernetShield)) or [CC3000](http://www.ti.com/product/cc3000)-based WIFI Shield.
-
-## Build and run instructions:
-
-###To run with Arduino Ethernet (W5100) shield:
-1. Add (Sketch->Add file...) the following files to sketch:
-     - /mongoose/mongoose.h
-     - /mongoose/mongoose.c
-     - /mongoose/platforms/arduino_ethernet_W5100/avrsupport.h
-     - /mongoose/platforms/arduino_ethernet_W5100/avrsupport.cpp
-3. Buils and start (in console) /Users/alex/Projects/mongoose/examples/restful_server example
-4. Make `board_ip` and `board_mac` variables suitable for your network and board
-5. Change IP address in `s_target_address` variable to IP address of host running restful_server
-6. Uncomment line `#include <Ethernet.h>`
-7. Compile and flash sketch
-8. restful_server will start to show current uptime and free memory size (with 5 seconds interval)
-
-###To run with Adafruit WiFi (CC3000) shield:
-1. Add (Sketch->Add files...) the following files to sketch:
-     - /mongoose/mongoose.h
-     - /mongoose/mongoose.c
-     - /mongoose/platforms/arduino_ethernet_W5100/avrsupport.h
-     - /mongoose/platforms/arduino_ethernet_W5100/avrsupport.cpp
-2. Import Adafruit CC3000 library for mongoose
-    (select Sketch->Import Library...->Add library... and point
-     /mongoose/platforms/arduino_wifi_CC3000/adafruit_CC3000_lib_mongoose folder)
-3. Buils and start (in console) /Users/alex/Projects/mongoose/examples/restful_server example
-4. Make the following variables suitable for your network
-     - `board_ip`
-     - `subnet_mask`
-     - `gateway`
-     - `dns`
-     - `wlan_ssid`
-     - `wlan_pwd`
-     - `wlan_security`
-5. Change IP address in `s_target_address` variable to IP address of host running restful_server
-6. Uncomment line `#include <Adafruit_CC3000.h>`
-8. Compile and flash sketch
-9. restful_server will start to show current uptime and free memory size (with 5 seconds interval)
