Hi, I would like to have a try. Do we have the preferred frameworks? e.g. Hugo / MkDocs etc.

Thanks @rudeigerc let's employ Hugo as both belong to golang ecosystem, and I think envoy gateway is a good example , we need to have the capacity of version manage. Glad to hear your advices.

I also think Hugo with the docsy theme is a nice choice since other Kubernetes SIGs projects, such as Kueue and LWS, apply this template as well.

We could initialize the site with basic content and styles first, then import the support for multiversions following the separated modifications, since Hugo does not support multiversions natively. Looking forward to the feedback :) @kerthcet

Make sense to me, let's go with hugo then.
