# Open Source Licences

### GPL&#x20;

A GPL license outlines the conditions for sharing, modifying, and copying open-source software. It is a true free code that you can modify and distribute. Linux, Git, and WordPress all use GPL licenses. GPL licenses require that the source code be available when you post it. Developers also must include an explanation of all the code they changed. &#x20;

### MIT&#x20;

The MIT license puts very few restrictions on software and is very popular for short and small open-source code. 31% of small projects use this license, and software like Node.js, Ruby, and the .Net framework all use it. It is the most used license on GitHub.&#x20;
