 description: Because copyright is automatic in most countries, <a href="http://unlicense.org">the Unlicense</a> is a template to waive copyright interest in software you've written and dedicate it to the public domain. Use the Unlicense to opt out of copyright entirely. It also includes the no-warranty statement from the MIT/X11 license.
 
 how: Create a text file (typically named UNLICENSE or UNLICENSE.txt) in the root of your source code and copy the text of the license disclaimer into the file.
