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 (1) code (i.e., the code under the copyright of the MathJax consortium, including extensions in the core repository) as well as third party extensions (2), translations and similar additions. Essentially, the difference between the two is that type (1) contributions cannot be removed without compromising MathJax as a whole while type (2) contribution can be removed without compromising the rest.

Contributions of type (2) 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 MathJax (e.g., via a pull request) should be sufficient.

If you want to contribute to the core of MathJax, please sign the CLA at http://www.mathjax.org/cla. You will receive a confirmation email after signing. If you are submitting code as an employee of another entity, we'll get in touch with you to sort out the details.

Thank you for contributing to MathJax!
