2. Definition
2.1. set of practices and principles aimed at building testing and releasing software faster and more frequently

3. Common Misconceptions
3.1. is something only startups can achieve
3.2. only works for NodeJs/ Ruby / Go .. or wtv language picked
3.3. we can hire a consultant to help us implement 'Continuous Delivery'

3.5. is as simple as hooking github to our Azure account
4. "Until your pretty code is in production, making money, or doing whatever it does, you've just wasted your time"
