 # assign-reviewer
-this action help to assign your coworkers as pull request reviewer if condition's matched.
+
+github only support [codeowner](https://docs.github.com/en/repositories/managing-your-repositorys-settings-and-features/customizing-your-repository/about-code-owners) currently. You can add a group of users as owner of specific folders or files.
+
+But often, there're some features which will cross lots of files, like "telemetry", "log", etc. For some teams or company, there always be so called "Feature Owner" to own specific feature. And their coworkers will make Pull Request to contribute. This action will help to assign "Feature Owner" as reviewer of your Pull Request.
