 Simple API for communicating with the bot of the \"iii.ru\" service.

+[forum](http://forum.iii.ru/index.php?showtopic=19886).
 
 ## Features
 - A small and light library.
@@ -18,39 +17,54 @@ npm install --save iii-client
 ```
 
 ## Using
-To use the bot will require identification number. The bot address can be of two kinds: `http://iii.ru/inf/109cd867-0ef3-4473-af71-7543a9b2fccd` and `http://109cd867-0ef3-4473-af71-7543a9b2fccd.iii.ru/`. In the address line, the value `109cd867-0ef3-4473-af71-7543a9b2fccd` is the bot identification number.
-
 An example of a connection, receiving session identification and sending a bot message:
 ```javascript
-import bot from 'iii-client';
+import client from 'iii-client';
 
-var uuid = '109cd867-0ef3-4473-af71-7543a9b2fccd';
+const uuid = '109cd867-0ef3-4473-af71-7543a9b2fccd';
+const text = 'Hello, World!';
 
 // We connect to the system and get a session
-bot.connect(uuid, function(data) {
+client.connect(uuid).then(session => {
-    const options = {
-        cuid: data.cuid,
-        text: 'Проверка связи. Ты получил моё сообщение?',
-    }
-
     // Send the message and process the response
-    bot.send(options, function(raw) {
+    client.send(session.cuid, text).then(answer => {
-        console.log(raw);
+        console.info(answer);
-    });
     });
+}).catch(error => console.error(error.message));
 ```
