# Know the license: GPLv3.

The Interactive Video Grid is licensed under **GPLv3**.

GPLv3, short for GNU General Public License version 3, is like a rulebook for software sharing. It says that **anyone can use, change or share the software**, but, being a "copyleft" license, if you do, you have to **let others do the same with your changes**. 

In other words, GPLv3 is designed to **reject proprietary software** models.

When you "[fork](/interactive-video-grid/the-extra-mile-publish-your-project-online./1.-fork-a-github-repository..md)" a GPLv3 project, it's like making your own version of the software. You can add new stuff or fix things you don't like. But, because of the GPLv3 rulebook, you have to keep your version open for others to use, change and share just like you did.
