## Step：

# 1. SkyWawlking-Manager Init
**You must init skywawlking manager pkg which will manage connection and report msg to skywalking**
- For example:
- [1] You can import skywalking manager proxy/pkg/skywalking in file proxy/bootstrap/bootstrap.go.
- [2] Calling function Init() in proxy/pkg/skywalking manually to init skywalking manager.
- [3] Adding skywalking's consumer handler name SkyWalkingConsumer defined in proxy/pkg/skywalking to consumerChain.
- [4] Adding skywalking's provider handler name SkyWalkingProvider defined in proxy/pkg/skywalking to providerChain.
- more details about handler chains in [go-chassis](https://github.com/go-chassis/go-chassis#readme)

# 2. SkyWalking-Handler Init
- You must import proxy/handler pkg to init skywalking handler. Not only skywalking handler, all the handlers which are customized for mesher are defined here.
- For example you can import handler pkg in file cmd/mesher/mesher.go
