+RE-Mote IP64 README file
+========================
+
+This example shows how to use the Zolertia's Orion Ethernet router, based on the Zoul and ENC28J60 modules, with active POE support.
+
+IP64 router
+-----------------
+The router packs a built-in webserver and optionally can run on 2.4GHz or with the Sub-1GHz radio interface.  In the `project-conf.h` file you can alternatively enable one or another as follows:
+
+* RF 2.4GHz (cc2538 built-in)
+
+````
+#define NETSTACK_CONF_RADIO         cc2538_rf_driver
+#define ANTENNA_SW_SELECT_DEF_CONF  ANTENNA_SW_SELECT_2_4GHZ
+````
+
+* RF Sub-1GHz (CC1200)
+
+````
+#define NETSTACK_CONF_RADIO         cc1200_driver
+#define ANTENNA_SW_SELECT_DEF_CONF  ANTENNA_SW_SELECT_SUBGHZ
+````
+
+To compile and flash run:
+
+````
+cd ip64-router
+make TARGET=zoul BOARD=router ip64-router.upload
+````
+
+As default we enable the `DHCP` support for autoconfiguration.  Just connect to a DHCP-enabled device to obtain an IPv4 IP address and that's it!.
+
+HTTP client examples
+-----------------
+
+There are available 2 examples ready to use using the `http-socket` library:
+
+* The `client` example just makes a HTTP `GET` request to a know page and retrieves
+  the result.
+
+* The `ifttt-client` example sends a HTTP `POST` request to [IFTTT](https://ifttt.com/recipes) whenever the user button is pressed, building an Internet button to connect to several channels and applications, such as `Drive`, `Evernote` and many others.
+
+To configure the `IFTTT` demo just edit the `project-conf.h` file and change the name of the event and write your API key:
+
+````
+#define IFTTT_EVENT   "button"
+#define IFTTT_KEY     "XXXXXX"
+````
+
+To compile and flash:
+
+````
+cd client
+make TARGET=zoul ifttt-client.upload
+````
+
