 ## 案例背景
 
-- 本用例主要是帮助用户快速入门**mersher sidecar模式**;希望用户通过该例子,快速上手使用mersher服务,了解mersher的工作模式,并了解如何通过mersher的帮助改造已有的http服务,接入ServiceComb微服务体系,得到go-chassis微服务框架提供的负载均衡、流控、服务治理、调用链追踪等微服务能力。

 ## Background
 
-- This use case is mainly to help users get started quickly with **mersher sidecar mode**. We hope that users can understand the working mode of mersher and learn how to merge the existing http service into the ServiceComb micro-service system with mersher's help. The final goal is to help user get the micro-service capabilities such as load balancing, flow control, service management and call chain tracing provided by servicecomb.
