+Indicate which version of `client-go` your project requires:

+- If you are using Kubernetes versions >= `v1.17.0`, use a corresponding
+`v0.x.y` tag. For example, `k8s.io/[email protected]` corresponds to Kubernetes `v1.17.0`:
 
 ```sh
-go get k8s.io/[email protected]
+go get k8s.io/[email protected]
+```
+
+You can also use a non-semver `kubernetes-1.x.y` tag to refer to a version
+of `client-go` corresponding to a given Kubernetes release. Prior to Kubernetes
+`v1.17.0` these were the only tags available for use with go modules.
+For example, `kubernetes-1.16.3` corresponds to Kubernetes `v1.16.3`.
+However, it is recommended to use semver-like `v0.x.y` tags over non-semver
+`kubernetes-1.x.y` tags to have a seamless experience with go modules.

+- If you are using Kubernetes versions < `v1.17.0` (replace `kubernetes-1.16.3` with the desired version):

+go get k8s.io/[email protected]
 ```
 
 You can now import and use the `k8s.io/client-go` APIs in your project.
 The next time you `go build`, `go test`, or `go run` your project,
 `k8s.io/client-go` and its dependencies will be downloaded (if needed),
 and detailed dependency version info will be added to your `go.mod` file
-(or you can also run `go mod tidy` to do this directly).
