-# Utils
-
-[![Build Status]](https://travis-ci.org/kubernetes/utils) [![GoDoc](https://godoc.org/k8s.io/utils?status.svg)](https://godoc.org/k8s.io/utils)
-
-A set of Go libraries that provide low-level,
-kubernetes-independent packages supplementing the [Go
-standard libs].
-
-## Purpose
-
-As Kubernetes grows and spins functionality out of its
-[core] and into cooperating repositories like
-[apiserver], [kubectl], [kubeadm], etc., the need
-arises for leaf repositories to house shared code and
-avoid cycles in repository relationships.
-
-This repository is intended to hold shared utilities
-with no Kubernetes dependence that may be of interest
-to any Go project. See these [instructions for moving]
-an existing package to this repository.
-
-
-## Criteria for adding code here
-
-- Used by multiple Kubernetes repositories.
-
-- Full unit test coverage.
-
-- Go tools compliant (`go get`, `go test`, etc.).
-
-- Complex enough to be worth vendoring, rather than copying.
-
-- Stable, or backward compatible, API.
-
-- _No dependence on any Kubernetes repository_.
-
-## Libraries
-
-- [Exec](/exec) provides an interface for `os/exec`. It makes it easier
- to mock and replace in tests, especially with
- the [FakeExec](exec/testing/fake_exec.go) struct.
-
-- [Temp](/temp) provides an interface to create temporary directories. It also
- provides a [FakeDir](temp/temptest) implementation to replace in tests.
-
-- [Clock](/clock) provides an interface for time-based operations. It allows
- mocking time for testing.
