# Kubernetes hack GuideLines

This document describes how you can use the scripts from [`hack`](.) directory 
and gives a brief introduction and explanation of these scripts. 

## Overview

The [`hack`](.) directory contains many scripts that ensure continuous development of kubernetes, 
enhance the robustness of the code, improve development efficiency, etc. 
The explanations and descriptions of these scripts are helpful for contributors.
