Deploy means "Uploading the model to your existing site". If you do not have an existing site (a web site that shall run the application) you can easily set one up. Once you upload your model it is received by a MDrivenServer instance. The MDrivenServer evolves the database (changes the sql script to match your uploaded model). Once this is done all your users see the new updated system when they point a browser to your sites url.
Step2: Log in on portal.mdriven.net
Step3 & Step4: Pick the site/slot to house your system
Step5 : Upload your current model
Now your deployed system is available for the world to use on any device with a browser. And you can continue to improve the model as you see fit.
