## What it is
Kubernetes' official Go code generators for building Kubernetes-style API types, producing typed clients, informers, listers, deepcopy functions, and conversion/defaulting code. It is a read-only staged repository synced from the main kubernetes/kubernetes repo.

## Use cases
- generate typed Go clients for my CustomResourceDefinition
- scaffold informers and listers for a Kubernetes controller
- generate deepcopy and conversion functions for API types
- build a Kubernetes-style API server with versioned clients
- write an operator without hand-writing client code

## When to choose
- you are developing Kubernetes CRDs or controllers in Go and need clients, informers, and listers
- you are building an aggregated API server following Kubernetes API conventions
- you want the canonical, upstream-supported code generation tooling for k8s-style APIs

## When to avoid
- you are not working with Kubernetes-style APIs or Go
- you want a general-purpose code generator unrelated to Kubernetes API machinery
- you need to file issues or contribute directly - contributions go to kubernetes/kubernetes

## Facets
- artifact type: library
