description: A permissive license lets people do anything with your code with proper attribution and without warranty. The ISC license is functionally equivalent to the <ahref="/licenses/bsd">BSD 2-Clause</a> and <ahref="/licenses/mit">MIT</a> licenses, removing some language that is no longer necessary.
how: Create a text file (typically named LICENSE or LICENSE.txt) in the root of your source code and copy the text of the license into the file. Replace [year] with the current year and [fullname] with the name (or names) of the copyright holders.
