-# Linting
-
-This document describes how to use the standalone linting tool to validate your Prometheus Operator [CRD-based](../design.md) configuration files.
-
-## Getting linter
-
-To use the linter either get it with `go get -u github.com/prometheus-operator/prometheus-operator/cmd/po-lint` and executable is `$GOPATH/bin/po-lint`, or use the container image from `quay.io/coreos/po-tooling` and executable is `/go/bin/po-lint`.
-
-## Using linter
-
-The `po-lint` executable takes a list of yaml files to check as command arguments. It will output any errors to stderr and returns with exit code `1` on errors, `0` otherwise.
-
-## Example
-
-Here is an example script to lint a `src` sub-directory full of Prometheus Operator CRD files with ether local `po-lint` or Dockerized version:
-
-```sh
-#!/bin/sh
-
-LINTER="quay.io/coreos/po-tooling"
-
-lint_files() {
-  if [ -x "$(command -v po-lint)" ]; then
-    echo "Linting '${2}' files in directory '${1}'..."
-    had_errors=0
-    for file in $(find "${1}" -name "${2}"); do
-      echo "${file}"
-      po-lint "${file}"
-      retval=$?
-      if [ $retval -ne 0 ]; then
-        had_errors=1
-      fi
-    done
-    exit ${had_errors}
-  elif [ -x "$(command -v docker)" ]; then
-    echo "Using Dockerized linter."
-    docker run --rm --volume "$PWD:/data:ro" --workdir /data ${LINTER} \
-    /bin/bash -c "/go/bin/po-lint $1/$2"
-  else
-    echo "Linter executable not found."
-    exit 1
-  fi
