Design Patterns Journal

Intro

The idea for this project is make and introduction for a better software development, starting with the key-concepts of a good piece of software, starting with what concepts do you need for start!

This "guide" (if it can be called that way) it is thought to people who knows how to program in at least one language, so I will not talk about simple things like arrays or functions.

So, Let's Start!.
