-***KubeSphere*** is a distribution of [Kubernetes](https://kubernetes.io), aimed to provide quick setup, friendly and easily use, and powerful management features for Kubernetes clusters, which could help both personal and enterprise users, reduce their learning curve of Kubernetes, accelerate their transform process from other container platforms to Kubernetes.   
-
-**Features:**
- - Multiple IaaS platform support, including baremetal/KVM/QingCloud, and more will be supported in future release.  
- - Easy setup of Kubernetes standalone(only one master node) and cluster environment(including High Availability support).  
- - Powerful management console to help business users to manage and monitor the Kubernetes.  
- - Integrate with [OpenPitrix](https://github.com/openpitrix) to provide full life cycle of application management and be compatible of helm package.  
- - Support popular open source network solutions, including calico and flannel, also could use [qingcloud hostnic solution](https://github.com/yunify/hostnic-cni) if the Kubernetes is deployed on QingCloud platform.  
- - Support popular open source storage solutions, including Glusterfs and Cephfs, also could use [qingcloud storage solution](https://github.com/yunify/qingcloud-csi) or [qingstor storage solution](https://github.com/yunify/qingstor-csi) if the Kubernetes is deployed on QingCloud platform or QingStor NeonSAN.  
- - CI/CD support.  
- - Service Mesh support.  
- - Multiple image registries support.  
- - Integrate with QingCloud IAM.

+## What is KubeSphere
+
+[KubeSphere](https://kubesphere.io/) is an enterprise-grade multi-tenant container management platform that built on [Kubernetes](https://kubernetes.io). It provides an easy-to-use UI enables creation of computing resources with a few clicks and one-click deployment, which reduces the learning curve and empower the DevOps teams. It greatly reduces the complexity of the daily work of development, testing, operation and maintenance, aiming to solve the pain spots of Kubernetes' storage, network, security and ease of use, etc.
+
+> See this [document](https://docs.kubesphere.io/advanced-v1.0/en/introduction/intro/) that describes the KubeSphere landscape and details.
+
+## Features
+
+KubeSphere provides an easy-to-use console with the awesome user experience that allows you to quickly get started with a container management platform. KubeSphere provides and integrates workload management, DevOps Delivery, multi-tenant management, multi-dimensional monitoring, service and network management, application scheduling, infrastructure management, image registry management, etc. It also supports multiple open source storage and high-performance cloud storage as the persistent storage services.
+
+> See this [document](https://docs.kubesphere.io/advanced-v1.0/en/introduction/features/) that elaborates on the KubeSphere features and services from a professional point of view.

-## Motivation
+## Installation
+
+KubeSphere installation supports following 2 kinds of installation:
+
+- [All-in-One](https://docs.kubesphere.io/advanced-v1.0/en/installation/all-in-one/): For those who are new to KubeSphere and looking for the fastest way to install and experience the dashboard, the all-in-one installation must be your best choice since it supports one-click installation.
+- [Multi-Node](../https://docs.kubesphere.io/advanced-v1.0/en/installation/multi-node/): Multi-node is used for installing KubeSphere on multiple instances, supports for installing a highly available master and etcd cluster which is able to use in a formal environment.
+- For Chinese version, see [KubeSphere Installation Guide (安装指南) ](https://docs.kubesphere.io/advanced-v1.0/zh-CN/installation/intro/).
+
+### Minimum Requirements
+
+- perating Systems
+   - CentOS 7.5 (64 bit)
+   - Ubuntu 16.04/18.04 LTS (64 bit)
+   - Red Hat Enterprise Linux Server 7.4 (64 bit)
+   - Debian Stretch 9.5 (64 bit)
+- Hardware
+   -CPU：4 Core,  Memory：8 G, Disk Space：100 G
 
-The project originates from the requirement and pains we heard from our customers on public and private QingCloud platform, who have strong will to deploy Kubernetes in their IT system but struggle on completed setup process and long learning curve. With help of KubeSphere, their IT operators could setup Kubernetes environment quickly and use an easy management UI interface to mange their applications, also KubeSphere provides more features to help customers to handle daily business more easily, including CI/CD, micro services management...etc.
+## Quick Start
 
-Getting Started
----------------
-**TBD**
+The [Quick Start Guide](https://docs.kubesphere.io/advanced-v1.0/en/quick-start/admin-quick-start/) provides 7 quick-start examples to walk you through the process and common manipulation in KubeSphere, with a quick overview of the basic features of KubeSphere that helps you to get familiar with it. 
 
-## Design
+## Latest Release
+
+KubeSphere Advanced Edition 1.0.1 was released on **January 28th, 2019**. See the [Release Notes For 1.0.1](https://docs.kubesphere.io/advanced-v1.0/en/release/release-v101/) to preview the updates.
+
+## RoadMap
