Contributor license agreement etc

MathJax is licensed under the Apache License 2.0.

Due to the modular structure of MathJax, contributions can come in two distinct forms: modifications of the core code (i.e., the code under the copyright of the MathJax consortium) as well as extensions, translations and other additions that can be removed easily.

Contributions of the second kind do not require a contributor license agreement (CLA) or copyright assignment agreement (CAA). Such contributions only require the Apache License 2.0. Because of Section 5 of the Apache License 2.0), the contributor’s active decision to submit code to the MathJax project should be sufficient.

If you want to contribute to the core of MathJax, please contact us.
