 # react-intro : Learning ReactJS
 
+This is the React comment box example from [the React tutorial](http://facebook.github.io/react/docs/tutorial.html).
+
 ## Installing
 
-- adjust the webpack-dev-server 2 URLs used in `index.html` :  `vm:8090` assumes
-  we want that server to run on a host called `vm`, but most users will want
-  `localhost` instead
-- adjust the `dev` script in `package.json` to match those URLs
-- `npm install`
-- `npm run start`
-- browse to [http://vm:8080/index.html](http://vm:8080/index.html) assuming
-  you didn't change the `serve` URL in `package.json`.
+```sh
+go run server.go
+```
+
+And visit <http://vm:3000/> assuming you host is called `vm`. Try opening multiple tabs!
+
+## Changing the port
+
+You can change the port number by setting the `$PORT` environment variable before invoking any of the scripts above, e.g.,
+
+```sh
+PORT=3001 node server.js
+```
