== Chapter 1: Start MDrivenDesigner, Basic Modeling, Classes, and Associations, Press Play ==
<blockquote>Throughout this training process, we'll familiarize you with the [[Training:MDriven Designer Overview Series|MDriven Designer]] using the example of a car management system. This includes creating elements like Cars and a Car Factory and adding people such as a Car Owner and Car Dealer. Every chapter adds a different piece to the overall system.  

Go to [https://mdriven.net/ mdriven.net] and let's begin!

'''<u>Option 1: (Blue)</u>''' 

Start MDrivenDesigner by clicking the "'''Run with ClickOnce'''" link at: https://mdriven.net/designer.

* You can choose to always run the MDriven Designer online using "'''Run with ClickOnce'''".
