Hello world!

Refactoring.Guru is a shiny website where you can find tons of information on refactoring, design patterns, SOLID principles and other smart programming topics.

The primary purpose of this site is to show the big picture. I want to demonstrate how all these subjects intersect, how they work together and how they are still relevant.

I don't pretend to be the inventor of these concepts. Most of them were invented by others during the past 20 years. But I think that the connection between refactoring, patterns and general programming principles still remains a mystery for the majority of programmers. And this is the problem I would like to solve here.

P.S. While the project is still a work in progress, you can already find lots of info on refactoring and design patterns. The progress can be tracked on the Facebook or by email.

Refactoring is a controllable process of improving code without creating new functionality. Refactoring transforms a mess into clean code and simple design.
