My experience contributing to Istio so far has been great. The CI is extremely fast, provides a lot of useful information (even the "generate check" command provides me a "git patch" command to fix directly things).
Seriously, very cool experience

Oooh this is nice. I know a lot of Kubernetes subprojects that use mkdocs + material, would for sure follow this effort!
Also links validations and better search ❤️

I've been a fan of Material for MkDocs since I was introduced to it through the stucco #powershell module. The stale upstream MkDocs community represented a lot of risk through, so the Material team have introduced a new SSG I'm excited to try. Faster builds and better live previews are 💪
Zensical – a modern static site generator.
We're excited to release @zensical.org, our new SSG that is compatible with Material for MkDocs:
– 5x faster rebuilds
– Modern design
– Blazing-fast search
