 ## Step2: Compile the target binary with otel
 Use `otel` to build the binary with `config.json`:
 ```
-cd example/extension/netHttp
+cd example/extension/nethttp
+../../../otel set -rule=config.json
 ../../../otel -rule=config.json go build demo/net_http.go
 ```
 Users can get the `otel` according to [documentation](../../../README.md)
