Thanks for taking the time to contribute!
The Trailblazer project has a simple Contributor License Agreement (CLA), following the “Inbound=Outbound” norm among open-source projects.
TRAILBLAZER CONTRIBUTOR LICENSE AGREEMENT
By agreeing to this Contributor License Agreement, you assign Trailblazer (Twingl Ltd.) copyright of your contributions (whether in the form of pull requests, patches, or Issues) on the condition that Trailblazer releases this code under the MIT License (the project’s outbound licence).
This does not preclude you from using your own contributions for any other purpose. Our intention with this CLA is that the project’s licensing remains simple and unambiguous.
