This list was originally a clone of StackOverflow - List of Freely Available Programming Books with contributions from Karan Bhangui and George Stocker.

The list was moved to GitHub by Victor Felder for collaborative updating and maintenance. It has grown to become one of GitHub's most popular repositories.

The Free Ebook Foundation now administers the repo, a not-for-profit organization devoted to promoting the creation, distribution, archiving, and sustainability of free ebooks. Donations to the Free Ebook Foundation are tax-deductible in the US.

🎉 Ultra-simplified explanation to design patterns! 🎉

A topic that can easily make anyone's mind wobble. Here I try to make them stick in to your
mind (and maybe mine) by explaining them in the simplest way possible

_{Check out my other project and say "hi" on Twitter.}

Design patterns are solutions to recurring problems; guidelines on how to tackle certain problems. They are not classes, packages or libraries that you can plug into your application and wait for the magic to happen. These are, rather, guidelines on how to tackle certain problems in certain situations.
