-# Contributor License Agreement
-
-Before we can accept your contributions to VyOS, you must sign a **Contributor
-License Agreement (CLA)**.
-
-This is a standard open-source practice that protects both you and the project.
-
-The process is straightforward and fully automated:
-
-1. **Review the CLA document**
-
-   Find the CLA text in our
-   [GitHub repository](https://github.com/vyos/vyos-cla-signatures/).
-
-2. **Submit a pull request**
-
-   When you open a pull request, a CLA bot automatically checks whether all
-   commit authors have signed the CLA.
-
-3. **Follow the bot's instructions**
-
-   If the CLA has not been signed, the bot leaves a comment with instructions.
-   Reply to that comment with the suggested text to sign the CLA.
-
-4. **Wait for confirmation**
-
-   The CLA bot verifies your response and updates the pull request status.
-   Once all commit authors have signed, the bot confirms that the CLA
-   requirement is met and unlocks the pull request for merging.
-
-:::{note}
-Each commit author must sign the CLA.
-
-If your pull request includes commits from multiple contributors, each one
-must sign the CLA before the pull request can be accepted.
-:::
-
-Once you sign the CLA, it remains valid for all your past and future
-contributions to VyOS under the same GitHub identity.
