 # 构建
 
-TDengine 目前可以在 Linux、 Windows、macOS 等平台上安装和运行。任何 OS 的应用也可以选择 taosAdapter 的 RESTful 接口连接服务端 taosd。CPU 支持 X64/ARM64，后续会支持 MIPS64、Alpha64、ARM32、RISC-V 等 CPU 架构。

 用户可根据需求选择通过源码、[容器](https://docs.taosdata.com/get-started/docker/)、[安装包](https://docs.taosdata.com/get-started/package/)或[Kubernetes](https://docs.taosdata.com/deployment/k8s/)来安装。本快速指南仅适用于通过源码安装。

 # Building
 
-At the moment, TDengine server supports running on Linux/Windows/macOS systems. Any application can also choose the RESTful interface provided by taosAdapter to connect the taosd service . TDengine supports X64/ARM64 CPU, and it will support MIPS64, Alpha64, ARM32, RISC-V and other CPU architectures in the future.
