this in other languages: [English](README.md), [中文](README_zh.md)._\n\nOpenELB is an open-source load balancer implementation designed for exposing the LoadBalancer type of Kubernetes services in bare metal, edge, and virtualization environments.\n\nOpenELB was originally created by [KubeSphere](https://kubesphere.io), and is currently a vendor neutral and CNCF [Sandbox Project](https://www.cncf.io/sandbox-projects/).\n\n## Why OpenELB\n\nIn cloud-based Kubernetes clusters, Services are usually exposed by using load balancers provided by cloud vendors. However, cloud-based load balancers are unavailable in bare-metal or on-premise environments. OpenELB allows users to create **LoadBalancer Services** in bare-metal, edge, and virtualization environments for external access, and provides the same user experience as cloud-based load balancers.\n\n## Core Features\n\n- Load balancing in BGP mode and Layer 2 mode\n- ECMP routing and load balancing\n- IP address pool management\n- BGP configuration using CRDs\n- Installation using Helm Chart\n\n## Quickstart\n\n- [Install OpenELB on Kubernetes](https://openelb.io/docs/getting-started/installation/install-openelb-on-kubernetes/)\n- [Install OpenELB on K3s](https://openelb.io/docs/getting-started/installation/install-openelb-on-k3s/)\n- [Install OpenELB on KubeSphere](https://openelb.io/docs/getting-started/installation/install-openelb-on-kubesphere/)\n\n## Documentation\n\nYou can learn how to use OpenELB in a cloud-based Kubernetes cluster by following the [OpenELB Documentation](https://openelb.io/docs/).\n\n## Adopters\n\nOpenELB has been adopted by [many companies](./ADOPTERS.md) all over the world. If you are using OpenELB in your organization, welcome to join the end user community and add your logo to the [list](./ADOPTERS.md)!\n\n## Roadmap\n\n[OpenELB Roadmap](docs/roadmap.md) lists the features and bug fixes for each milestone. If you have any new ideas, feature requests or suggestions, please submit a proposal.\n\n## Support, Discussion and Contributing\n\n- Join us at the [KubeSphere Slack Channel](https://kubesphere.slack.com/join/shared_invite/enQtNTE3MDIxNzUxNzQ0LTZkNTdkYWNiYTVkMTM5ZThhODY1MjAyZmVlYWEwZmQ3ODQ1NmM1MGVkNWEzZTRhNzk0MzM5MmY4NDc3ZWVhMjE#/) to get support or simply tell us that you are using OpenELB.(openelb slack channel from kubernetes will be soon)\n- You have code or documents for OpenELB? Contributions are always welcome! See [Building and Contributing](https://openelb.io/docs/building-and-contributing/) to obtain guidance.\n\n## License\n\nOpenELB is licensed under the Apache License, Version 2.0.
