+
+A package for generating things based on go files. This mechanism was first used
+in Kubernetes and is split out here for ease of reuse and maintainability.
+
+`go get k8s.io/gengo`
+
+## Examples
+
+A set generator, deep-copy generator, defaulter generator and go-to-protobuf
+generator are included here. Also, import-boss will enforce arbitrary rules about
+import trees.
+
+## args/
+
+Package args defines common arguments for a generator binary.
+
+## generator/
+
+Package generator defines interfaces for code generators to implement, and
+machinery that will execute those code generators.
+
+## types/
+
+Package types contains the type system definition. It is modeled after Go's type
+system, but it's intended that you could produce these types by parsing
+something else, if you want to write the parser/converter.
+
+We don't directly use the go types in the go typecheck library because they are
+based on implementing differing interfaces. A struct-based format is more
+convenient input for template driven output.
+
+## parser/
+
+Package parser parses go source files.
+
+## namer/
+
+Package namer defines a naming system, for:
+* helping you reference go objects in a syntactically correct way
+* keeping track of what you reference, for importing the right packages
+* and defining parallel tracks of names, for making public interfaces and
+  private implementations.
