 # dsoftbus
 
 #### 介绍
-openEuler embedded softbus capability support
+openEuler秉承着打造“数字化基础设施操作系统”的愿景，为促进与OpenHarmony生态的合作与互通，实现端边领域的互通和协同，首次在嵌入式领域引入分布式软总线技术。
+分布式软总线是OpenHarmony社区开源的分布式设备通信基座，为设备之间的互通互联提供统一的分布式协同能力，实现设备无感发现和高效传输。
+OpenHarmony主要面向强交互等需求的智能终端、物联网终端和工业终端。openEuler主要面向有高可靠、高性能等需求的服务器、边缘计算、云和嵌入式设备，二者各有侧重。通过以分布式软总线为代表的技术进行生态互通，以期实现“1+1>2”的效果，支撑社区用户开拓更广阔的行业空间。
