## Update generated files

Run `make update` to regenerate files if you make the following changes:

* Add/edit/remove command line flags and/or their help text
* Add/edit/remove commands or subcommands
* Add new API types

Run [generate-proto.sh][13] to regenerate files if you make the following changes:

* Add/edit/remove protobuf message or service definitions. These changes require the [proto compiler][14] and compiler plugin `protoc-gen-go` version v1.0.0.

The following files are automatically generated from the source code:

* The clientset
* Listers
* Shared informers
* Documentation
* Protobuf/gRPC types

You can run `make verify` to ensure that all generated files (clientset, listers, shared informers, docs) are up to date.

## Test

To run unit tests, use `make test`.

## Vendor dependencies

If you need to add or update the vendored dependencies, see [Vendoring dependencies][11].
