Hi @diwakar-s-maurya, yesterday we shared some updates with our contributors about how we're aiming to improve the contribution process. Part of this included the addition of a Contributor License Agreement (CLA) to protect both contributors and the project. We're reaching out to ask that previous contributors sign it.

Could you please take a moment to sign, or if you have any questions send me a message? (either here or [email protected] would work)

To do so, you just need to post a comment below with the following text:

I have read the CLA Document and I hereby sign the CLA

❤️ Thank you for the work you've done on Continue, and let me know if you have any suggestions on how we can make the project even better!
