 > **A:** The combination with shareable configs and plugins has some problems because shareable configs were not designed to be used with plugins. @nzakas illustrated a way to use plugins as shareable configs together with other plugins in the discussion [eslint/eslint#3458](https://github.com/eslint/eslint/issues/3458#issuecomment-257161846).
