Note to External Contributors

Hello, External Person!

We at Obvious are eager to work with you. For small changes — little bugfixes, correcting typos, and the like — please just submit pull requests to any of our projects. For larger changes, though, we have to ask you to jump through a little hoop.

In particular, in order for us to accept any major patches from you, you will have to electronically sign a statement that indicates two things:

  • You are willingly licensing your contributions under the terms of the open source license of the project that you're contributing to.

  • You are legally able to license your contributions as stated.

The reason we do this is to ensure, to the extent possible, that we don't "taint" the projects we manage with contributions that turn out to be improper. This protects everyone who wants to use the projects, including you! If you want a longer explanation, then you can check out the OCLA Rationale page.

Once you sign the Obvious Contributor License Agreement (the "OCLA"), we will then be able to merge your contributions with a clear conscience and with only the friction that results from the usual technical back-and-forth of a vibrant open source project.

To get started with this process, visit the Sign the OCLA page.

For reference, the standard open source license used by The Obvious Corporation is the Apache License 2.0 with a small clarifying preamble.

If you have any questions about any of this, please raise them by filing a bug on this project, since there's a good chance that if you have a question then someone else has the same question too. If it is really and truly a private matter, then you can mail Obvious's official Open Sourceror privately, at

Thanks, and happy hacking!
