This is my summary of the "Head First - Design Patterns", by Eric Freeman & Elisabeth Freeman.
I use it while learning and as quick reference. It is not intended to be an standalone substitution of the book so if you really want to learn the concepts here presented, buy and read the book and use this repository as a reference and guide.
If you are the publisher and think this repository should not be public, just write me on http://linkedin.com/in/stepasquini and I will make it private.
