+### parameter
 
-- `script` the path of js script.
-- `exec` your command.
-- `initRun` when init restartor, run it immediately or not.
-- `env` set environment variable with an object (don't use `set` in windows or `export` in linux to set environment with `exec`, it's useless).
+- `command`: it supports running commands directly which in `./node_modules/.bin/`, like `npm run`.
+- `env`: set environment variables with an object.
 
-NOTE: `script` and `exec`, just choose one. if you set both of them, exec will run.
