My understanding as per the website guidelines is that this is migration is not strictly required. However, we still want this to happen. The website is an important part to K3s and should get migrated. CNCF already owns the domain, we just haven't moved the project yet :)

While the k3s.io website is open and can be updated today, and while there doesn't appear to be any requirement to move the website itself to a CNCF owned neutral organization, I would still like to transfer the project over to k3s-io so its in a more logical place and thus easier for the community to make any necessary updates.

This will involve transferring the https://github.com/rancherlabs/k3s-website project over to https://github.com/k3s-io/k3s-website
