Too Long; Didn't Read
The Agile Manifesto is way too concise to explain software engineering. Founder at http://epek.app is trying to make it easier to understand. Here is the simple question: If you want to get Agile, start with mapping the principles to the status quo, and two simple questions: Does X seem to conform to the principles of Agile? If X seems like it sounds good, but how do we make it happen? Asking those two questions will get you started and get you farther than said.
