Complete the Fedora Project Contributor Agreement (FPCA)

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

Under Fedora Accounts page > Settings > Agreements, read through the Fedora Project Contributor Agreement. If you agree, click the Sign User Agreement button at the bottom.

The FPCA 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.
