 ## 开始使用
 OpenYurt 支持最高版本为1.16的 Kubernetes 。使用更高版本的 Kubernetes 可能会导致兼容性问题。
 您可以[手动](docs/tutorial/manually-setup.md)设置 OpenYurt 集群，但是我们建议使用 `yurtctl` 命令行工具启动 OpenYurt 。要快速构建和安装设置 `yurtctl` ，在编译系统已安装了 golang 1.13+ 和 bash 的前提下你可以执行以下命令来完成安装：

+## 资源要求
+我们强烈建议生产环境中的worker节点最少具备2核CPU和4GB内存。开发环境该限制可以放宽，但节点资源更少意味着留给workload的可用资源也更少。
+
+## 生产可用的系统和平台
+* CentOS 7.4及以上 (amd64、arm64)
+* Ubuntu 18.04及以上的LTS版本 (amd64、arm64)
+* Fedora 31 (amd64)
+* Debian 9.1 (amd64)
+
+其他的系统和平台可能也是生产可用的，但我们没有在生产环境做过验证，欢迎补充。

+# Resource and System Requirements
+
+## Resource Requirements
+We strongly recommend at least 2 CPUs and 4 GB RAM per worker node in production environment.
+Any less in development environment is ok but will leave little room for your workloads.
+
+## Tested Platforms
+* CentOS 7.4+ (amd64 and arm64)
+* Ubuntu 18.04 LTS+ (amd64 and arm64)
+* Fedora 31 (amd64)
+* Debian 9.1 (amd64)
+
+Other platforms may work well but are not tested in our production environment. Supplements to the list are welcome.
