 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. Essentially, the difference between the two is that the first type of contributions cannot be removed without compromising MathJax as a whole while the second type of contribution can be removed without compromising the rest.
 
-Contributions of the second kind do not require a [contributor license agreement (CLA)](https://en.wikipedia.org/wiki/Contributor_License_Agreement) or copyright assignment agreement (CAA). Such contributions only require the [Apache License 2.0](https://github.com/mathjax/MathJax/blob/master/LICENSE). Because of Section 5 of the [Apache License 2.0](https://github.com/mathjax/MathJax/blob/master/LICENSE)), the contributor’s active decision to submit code to the MathJax project should be sufficient.
