+# Twitter Binding
+
+The Twitter binding allows your home to Tweet 280 characters at a time. It also supports direct messages and tweeting with media.
+
+## Supported Things
+
+```
+account - Twitter Account.
+
+```
+
+## Thing Configuration
+
+The Twitter Account Thing requires you to create a Twitter App in the Twitter Developer Page.
+
+| Property | Default | Required | Description |
+|-------------------|---------|:--------:|-----------------------------------|
+| consumerKey | | Yes | Consumer API Key |
+| consumerSecret | | Yes | Consumer API Secret |
+| accessToken | | Yes | Access Token |
+| accessTokenSecret | | Yes | Access Token Secret |
+| refresh | 30 | No | Tweet refresh interval in minutes |
+
+
+## Channels
+
+| channel | type | description |
+|------------|--------|------------------------------------------------|
+| lasttweet | String | This channel provides the Latest Tweet message |
+
+
+## Full Example
+
+twitter.things:
+
+```
+Thing twitter:account:sampleaccount [ consumerKey="11111", consumerSecret="22222", accessToken="33333", accessTokenSecret="444444" ]
+
+```
+
+twitter.items:
+
+```
+String sample_tweet "Latest Tweet: [%s]" { channel="twitter:account:sampleaccount:lasttweet" }
+
+```
+
+## Rule Action
+
+This binding includes rule actions for sending tweets and direct messages.
+
+* `boolean success = sendTweet(String text)`
+* `boolean success = sendTweetWithAttachment(String text, String URL)`
+* `boolean success = sendDirectMessage(String recipientID, String text)`
+
+Examples:
+
+```
+val tweetActions = getActions("twitter","twitter:account:sampleaccount")
+val success = tweetActions.sendTweet("This is A Tweet")
+val success2 = tweetActions.sendTweetWithAttachment("This is A Tweet with a Pic", file:///tmp/201601011031.jpg)
+val success3 = tweetActions.sendTweetWithAttachment("Windows Picture", "D:\\Test.png" )
+val success4 = tweetActions.sendTweetWithAttachment("HTTP Picture", "http://www.mywebsite.com/Test.png" )
+val success5 = tweetActions.sendDirectMessage("1234567", "Wake Up" )
+
+```
