+# Running as Express Middleware
+
+Instead of starting Parse Dashboard with the CLI, you can also run it as an [express](https://github.com/expressjs/express) middleware.
+
+```
+var express = require('express');
+var ParseDashboard = require('parse-dashboard');
+
+var dashboard = new ParseDashboard({
+  "apps": [
+    {
+      "serverURL": "http://localhost:1337/parse",
+      "appId": "myAppId",
+      "masterKey": "myMasterKey",
+      "appName": "MyApp"
+    }
+  ]
+});
+
+var app = express();
+
+// make the Parse Dashboard available at /dashboard
+app.use('/dashboard', dashboard);
+
+var httpServer = require('http').createServer(app);
+httpServer.listen(4040);
+```
+
+If you want to run both [Parse Server](https://github.com/ParsePlatform/parse-server) and Parse Dashboard on the same server/port, you can run them both as express middleware:
+
+```
+var express = require('express');
+var ParseServer = require('parse-server').ParseServer;
+var ParseDashboard = require('parse-dashboard');
+
+var api = new ParseServer({
+	// Parse Server settings
+});
+
+var dashboard = new ParseDashboard({
+	// Parse Dashboard settings
+});
+
+var app = express();
+
+// make the Parse Server available at /parse
+app.use('/parse', api);
+
+// make the Parse Dashboard available at /dashboard
+app.use('/dashboard', dashboard);
+
+var httpServer = require('http').createServer(app);
+httpServer.listen(4040);
