-[KubeSphere](https://kubesphere.io/) is a multi-tenant enterprise-grade container platform built on [Kubernetes](http://kubernetes.io), with full-stack automated IT operation and streamlined DevOps workflows. KubeSphere provides developer-friendly wizard web UI, helping enterprises to build out a more robust and feature-rich platform, which includes most common functionalities needed for enterprise Kubernetes strategy, such as the **Kubernetes resource management, DevOps (CI/CD), application lifecycle management, monitoring, logging, Service Mesh (Istio-based), multi-tenancy, alerting and notification, storage and networking, autoscaling, access control, GPU support, etc.**, as well as **multi-cluster management, Network Policy, registry management, more security enhancements** in upcoming releases. KubeSphere is a **distributed operating system with cloud native stack** with Kubernetes as its kernel, and will be very well architected for **plug-and-play integration for third-party applications to boost its ecosystem**.
+[KubeSphere](https://kubesphere.io/) is a **distributed operating system providing cloud native stack** with [Kubernetes](https://kubernetes.io) as its kernel, and aims to be plug-and-play architecture for third-party applications seamless integration to boost its ecosystem. KubeSphere is also a multi-tenant enterprise-grade container platform with full-stack automated IT operation and streamlined DevOps workflows. It provides developer-friendly wizard web UI, helping enterprises to build out a more robust and feature-rich platform, which includes most common functionalities needed for enterprise Kubernetes strategy, see [Feature list](#features) for details.
 
-KubeSphere provides a complete user experience around Kubernetes that incorporates a set of cloud native ecosystem tools, allowing developers and DevOps teams use their favorite tools in a unified console. KubeSphere delivers **consolidated views while integrating a wide breadth of ecosystem tools** around Kubernetes and offers consistent user experience to reduce complexity. Most importantly, these functionalities are loosely coupled with the platform since they are pluggable and optional at your will. Last but not least, it does not change Kubernetes itself anything. In another word, KubeSphere can be deployed on any existing version-compatible Kubernetes cluster.
