+Your application should run on port 3000 with the *development* environment configuration, so in your browser just go to [http://localhost:3000](http://localhost:3000)
 
 That's it! Your application should be running. To proceed with your development, check the other sections in this documentation.

+### Running in Production mode
+To run your application with *production* environment configuration, execute grunt as follows:
+```bash
+$ grunt prod
+```
+* explore ```config/env/production.js``` for production environment configuration options
+
+### Running with TLS (SSL)
+Application will start by default with secure configuration (SSL mode) turned on and listen on port 8443.
+To run your application in a secure manner you'll need to use OpenSSL and generate a set of self-signed certificates. Unix-based users can use the following command:
+```bash
+$ sh ./scripts/generate-ssl-certs.sh
+```
+Windows users can follow instructions found [here](http://www.websense.com/support/article/kbarticle/How-to-use-OpenSSL-and-Microsoft-Certification-Authority).
+After you've generated the key and certificate, place them in the *config/sslcerts* folder.
+
+Finally, execute grunt's prod task ```grunt prod```
+* enable/disable SSL mode in production environment change the ```secure``` option in ```config/env/production.js```

 ## Testing Your Application
 You can run the full test suite included with MEAN.JS with the test task:
 
-```
+```bash
 $ grunt test
 ```
 
 This will run both the server-side tests (located in the app/tests/ directory) and the client-side tests (located in the public/modules/*/tests/).
 
 To execute only the server tests, run the test:server task:
 
-```
+```bash
 $ grunt test:server
 ```
 
 And to run only the client tests, run the test:client task:
 
-```
+```bash
 $ grunt test:client
 ```

 ## Getting Started With MEAN.JS
 You have your application running, but there is a lot of stuff to understand. We recommend you go over the [Official Documentation](http://meanjs.org/docs.html).
 In the docs we'll try to explain both general concepts of MEAN components and give you some guidelines to help you improve your development process. We tried covering as many aspects as possible, and will keep it updated by your request. You can also help us develop and improve the documentation by checking out the *gh-pages* branch of this repository.
