-# connect-flash
-
-The flash is a special area of the session used for storing messages. Messages
-are written to the flash and cleared after being displayed to the user. The
-flash is typically used in combination with redirects, ensuring that the message
-is available to the next page that is to be rendered.
-
-This middleware was extracted from [Express](http://expressjs.com/) 2.x, after
-Express 3.x removed direct support for the flash. connect-flash brings this
-functionality back to Express 3.x, as well as any other middleware-compatible
-framework or application. +1 for [radical reusability](http://substack.net/posts/b96642/the-node-js-aesthetic).
-
-## Install
-
- $ npm install connect-flash
-
-## Usage
-
-#### Express 3.x
-
-Flash messages are stored in the session. First, setup sessions as usual by
-enabling `cookieParser` and `session` middleware. Then, use `flash` middleware
-provided by connect-flash.
-
-```javascript
-var flash = require('connect-flash');
-var app = express();
-
-app.configure(function() {
- app.use(express.cookieParser('keyboard cat'));
- app.use(express.session({ cookie: { maxAge: 60000 }}));
- app.use(flash());
-});
-```
-
-With the `flash` middleware in place, all requests will have a `req.flash()` function
-that can be used for flash messages.
-
-```javascript
-app.get('/flash', function(req, res){
- // Set a flash message by passing the key, followed by the value, to req.flash().
- req.flash('info', 'Flash is back!')
- res.redirect('/');
-});
-
-app.get('/', function(req, res){
- // Get an array of flash messages by passing the key to req.flash()
- res.render('index', { messages: req.flash('info') });
-});
-```
-
-## Examples
-
-For an example using connect-flash in an Express 3.x app, refer to the [express3](https://github.com/jaredhanson/connect-flash/tree/master/examples/express3)
-example.
-
-## Tests
