+HTTP Request library for Arduino and the ESP8266 WiFi SOC modules
+
+This library now supports SSL!  To use with SSL, you need to include the SHA1 fingerprint of the certificate of the site you are connecting to.  You can get this by using a desktop browser and inspecting the SSL cert used at the site.  Please note: this is FRAGILE, if the site updates their SSL, your code will break.  But, there is not enough memory on the ESP8266 to store all the rool certs, so this is a working method.  Se the example below.
+
+This library is derived almost entirely from the great work done here: https://github.com/csquared/arduino-restclient

 # Usage
 
 ### Include
 
-You need to have the `Ethernet` library already included.
-
-```c++
-#include <Ethernet.h>
-#include <SPI.h>
-#include "RestClient.h"

-### dhcp()
-
-Sets up `EthernetClient` with a mac address of `DEADBEEFFEED`. Returns `true` or `false` to indicate if setting up DHCP

-
-```c++
-  client.dhcp()

-
-Note: if you have multiple Arduinos on the same network, you'll need
-to give each one a different mac address.

-### begin(byte mac[])
-
-It just wraps the `EthernetClient` call to `begin` and DHCPs.
-Use this if you need to explicitly set the mac address.
-
+Use a local IP, an explicit port to an SSL site and (must include the 1 to turn on SSL):
 ```c++
-  byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
-  if (client.begin(mac) == 0) {
-     Serial.println("Failed to configure Ethernet using DHCP");

+Use a local IP, an explicit port to an SSL site and verify the certificate with its fingerprint:
