I had a quick question regarding copyright section, should we either follow this convention e.g. "2026 © The PipeCD Authors."

followed by the other CNCF project websites and other standard websites, e.g.

@nthapa000 thanks for this change, to answer your question going with what other projects are already using sounds a better option for me!

I have some additions to this. If Pipecd is an open source project, adding the term "All right reserved" nullifies the project's purpose.

Copyright attribution follows the format: " copyright [year of granting copyright] [copyright holder(s)]".

Consult the project's license to know who the copyright holder is to avoid legal implications.

the format you already have ("© 2026 The PipeCD Authors") is the same one Kubernetes uses in their footer, so I think it's is good either way
