+TwitterOAuth
+------------
+
+PHP library for working with Twitter's OAuth API.
+
+Flow Overview
+=============
+
+1. Build TwitterOAuth object using client credentials.
+2. Request temporary credentials from Twitter.
+3. Build authorize URL for Twitter.
+4. Redirect user to authorize URL.
+5. User authorizes access and returns from Twitter.
+6. Rebuild TwitterOAuth object with client credentials and temporary credentials.
+7. Get token credentials from Twitter.
+8. Rebuild TwitterOAuth object with client credentials and token credentials.
+9. Query Twitter API.
+
+Terminology
+===========
+
+The terminology has changed since 0.1.x to better match the draft-hammer-oauth IETF
+RFC. You can read that at http://tools.ietf.org/html/draft-hammer-oauth. Some of the
+terms will differ from those Twitter uses as well.
+
+client credentials - Consumer key/secret you get when registering an app with Twitter.
+temporary credentials - Previously known as the request token.
+token credentials - Previously known as the access token.
+
+Parameters
+==========
+
+There are a number of parameters you can modify after creating a TwitterOAuth object.
+
+The latest reveissions of TwitterOAuth support the Twitter API v1.1 but if you want to
+update an old install from v1.0 you can do the following.
+
+    $connection->host = "https://api.twitter.com/1.1/";
+
+Custom useragent.
+
+    $connection->useragent = 'Custom useragent string';
+
+Verify Twitters SSL certificate.
+
+    $connection->ssl_verifypeer = TRUE;
+
+There are several more you can find in TwitterOAuth.php.
+
+Extended flow using example code
+================================
+
+To use TwitterOAuth with the Twitter API you need *TwitterOAuth.php*, *OAuth.php* and
+client credentials. You can get client credentials by registering your application at
+[dev.twitter.com/apps](https://dev.twitter.com/apps).
+
+Users start out on connect.php which displays the "Sign in with Twitter" image hyperlinked
+to redirect.php. This button should be displayed on your homepage in your login section. The
+client credentials are saved in config.php as `CONSUMER_KEY` and `CONSUMER_SECRET`. You can
+save a static callback URL in the app settings page, in the config file or use a dynamic
+callback URL later in step 2. In example use https://example.com/callback.php.
+
+1) When a user lands on redirect.php we build a new TwitterOAuth object using the client credentials.
+If you have your own configuration method feel free to use it instead of config.php.
+
+    $connection = new TwitterOAuth(CONSUMER_KEY, CONSUMER_SECRET); // Use config.php client credentials
+    $connection = new TwitterOAuth('abc890', '123xyz');
+
+2) Using the built $connection object you will ask Twitter for temporary credentials. The `oauth_callback` value is required.
+
+    $temporary_credentials = $connection->getRequestToken(OAUTH_CALLBACK); // Use config.php callback URL.
+
+3) Now that we have temporary credentials the user has to go to Twitter and authorize the app
+to access and updates their data. You can also pass a second parameter of FALSE to not use [Sign
+in with Twitter](https://dev.twitter.com/docs/auth/sign-twitter).
+
+    $redirect_url = $connection->getAuthorizeURL($temporary_credentials); // Use Sign in with Twitter
+    $redirect_url = $connection->getAuthorizeURL($temporary_credentials, FALSE);
+
+4) You will now have a Twitter URL that you must send the user to.
+
+    https://api.twitter.com/oauth/authenticate?oauth_token=xyz123
+
+5) The user is now on twitter.com and may have to login. Once authenticated with Twitter they will
+will either have to click on allow/deny, or will be automatically redirected back to the callback.
+
+6) Now that the user has returned to callback.php and allowed access we need to build a new
+TwitterOAuth object using the temporary credentials.
+
+    $connection = new TwitterOAuth(CONSUMER_KEY, CONSUMER_SECRET, $_SESSION['oauth_token'],
+    $_SESSION['oauth_token_secret']);
+
+7) Now we ask Twitter for long lasting token credentials. These are specific to the application
+and user and will act like password to make future requests. Normally the token credentials would
+get saved in your database but for this example we are just using sessions.
+
+    $token_credentials = $connection->getAccessToken($_REQUEST['oauth_verifier']);
+
+8) With the token credentials we build a new TwitterOAuth object.
+
+    $connection = new TwitterOAuth(CONSUMER_KEY, CONSUMER_SECRET, $token_credentials['oauth_token'],
+    $token_credentials['oauth_token_secret']);
+
+9) And finally we can make requests authenticated as the user. You can GET, POST, and DELETE API
+methods. Directly copy the path from the API documentation and add an array of any parameter
+you wish to include for the API method such as curser or in_reply_to_status_id.
+
+    $account = $connection->get('account/verify_credentials');
+    $status = $connection->post('statuses/update', array('status' => 'Text of status here', 'in_reply_to_status_id' => 123456));
+    $status = $connection->delete('statuses/destroy/12345');
