<h3><ahref="licenses/mit">I want it simple and permissive.</a></h3>
<p>
The <ahref="licenses/mit">MIT License</a> is a permissive license that is short and to the point. It lets people do anything they want with your code as long as they provide attribution back to you and don’t hold you liable.
<h3><ahref="licenses/apache">I’m concerned about patents.</a></h3>
<p>
The <ahref="licenses/apache/">Apache License</a> is a permissive license similar to the MIT License, but also provides an express grant of patent rights from contributors to users.
The GPL (<ahref="licenses/gpl-v2">V2</a> or <ahref="licenses/gpl-v3">V3</a>) is a copyleft license that requires anyone distributing the code, modified or not, to make the source available under the same terms to whomever they distribute to. V3 is similar to V2, but further restricts use in hardware that forbids software alterations.
