# Unlicense Yourself: Set Your Code Free

## What is the Unlicense?

The Unlicense is a template for [disclaiming copyright monopoly interest](http://cr.yp.to/publicdomain.html) in software you've written; in other words, it is a template for dedicating your software to the [public domain](http://stpeter.im/writings/essays/publicdomain.html). It combines a copyright waiver [patterned](http://ar.to/2010/01/dissecting-the-unlicense) after the [very successful](http://www.sqlite.org/famous.html) public domain [SQLite](http://www.sqlite.org/) project with the no-warranty statement from the widely-used [MIT/X11 license](http://en.wikipedia.org/wiki/MIT_License).

## Why Use the Unlicense?

Because you have more important things to do than enriching lawyers or imposing petty restrictions on users of your code. How often have you passed up on utilizing and contributing to a great software library just because its [open source](http://opensource.org/) license was not compatible with your own preferred [flavor](http://opensource.org/licenses/alphabetical) of open source? How many precious hours of your life have you spent deliberating how to license your software or worrying about licensing compatibility with other software? You will never get those hours back, but here's your chance to start cutting your losses. Life's too short, let's get back to coding.
