These are design documents for changes to Kubebuilder (and cross-repository changes for related projects, like controller-runtime and controller-tools). They exist to help document the design processes that go into writing Kubebuilder, but may not be up-to-date (more below).

Not all changes to Kubebuilder need a design document -- only major ones. Use your best judgement.

When submitting a design document, we encourage having written a proof-of-concept, and it's perfectly acceptable to submit the proof-of-concept PR simultaneously with the design document, as the proof-of-concept process can help iron out wrinkles and can help with the Example section of the template.

Kubebuilder documentation (the book and the GoDoc) should be considered the canonical, update-to-date reference and architectural documentation for Kubebuilder.

However, if you see an out-of-date design document, feel free to submit a PR marking it as such, and add an addendum linking to issues documenting why things changed. For example:

# Out of Date

This change is out of date.  It turns out curly braces are frustrating to
type, so we had to abandon functions entirely, and have users specify
custom functionality using strings of Common LISP instead.  See #000 for
more information.
