+### rpc vs. gRPC
+
+HttpRunner+ has both supported `net/rpc` and `gRPC` in [hashicorp/plugin]. It is recommended to use `gRPC` and this is the default choice.
+
+If you want to run plugin in `net/rpc` mode, you can set an environment variable `HRP_PLUGIN_TYPE=rpc`.

 The golang official plugin is only supported on Linux, FreeBSD, and macOS. And this solution also has many drawbacks.
