+## How to contribute to docs
+
+We currently have 2 production branches, `book-v2` and `book-v1`. `book-v2` maps
+to `book.kubebuilder.io` which contains our latest released features, while
+`book-v1` maps to `book-v1.book.kubebuilder.io`, which contains our legacy docs
+for kubebuilder V1.
+
+Docs for unreleased features live in the `master` branch. We merge the `master`
+branch into the `book-v2` branch when doing the releases.
+
+If adding doc for an unreleased feature, the PR should target `master` branch.
+If updating existing docs, the PR should target `master` branch and then
+cherry-picked into `book-v2` branch.
