You certify that:

•	Your Contributions are either:

  (described below); or
  2.	Based upon previous work that, to the best of your knowledge, is covered under an appropriate open 
  source license and you have the right under that license to submit that work with modifications, whether 
  created in whole or in part by you, under the designated license; or
  3.	Provided directly to you by some other person who certified (1) or (2) and you have not modified them.

•	You are granting your Contributions to the Allen Institute under the terms of the 2-Clause BSD license 
(the “designated license”).

•	You understand and agree that the Allen Institute projects and your Contributions are public and that a 
record of the Contributions (including all metadata and personal information you submit with them) is
