Complete the Contributor License Agreement

This is where you can complete the Contributor License Agreement from the Fedora Account System .

If you have not filled in a telephone number and address, you will be redirected to the edit page to add this information.

On the CLA page, read through the Contributor License Agreement, and if you agree, click the I Agree button at the bottom.

The CLA is required for new Fedora Project contributors to protect both the Contributor and the Fedora Project. It makes certain that Fedora can remain forever free & open source.

Red Hat employees do not need to complete the Fedora CLA.
Instead, you can request to join the cla_redhat group where you will be approved by someone verifying that you are employed by Red Hat.
