+### 5.xiii. How can I check Vue files with ESLint?
+
+To check Vue files with ESLint, your ESLint project configuration file must be
+configured to use the [Vue plugin](https://github.com/vuejs/eslint-plugin-vue).
+After that, you need to configure ALE so it will run the JavaScript ESLint
+linter on your files. The settings you need are similar to the settings needed
+for checking JSX code with both stylelint and ESLint, in the previous section.
+
+```vim
+" In ~/.vim/ftplugin/vue.vim, or somewhere similar.
+
+" Run both javascript and vue linters for vue files.
+let b:ale_linter_aliases = ['javascript', 'vue']
+" Select the eslint and vls linters.
+let b:ale_linters = ['eslint', 'vls']
+```
+
+Run `:ALEInfo` to see which linters are available after telling ALE to run
+JavaScript linters on Vue files. Not all linters support checking Vue files.
+
+If you don't want to configure your linters in ftplugin files for some reason,
+you can configure them from your vimrc file instead.
+
+```vim
+" In ~/.vim/vimrc, or somewhere similar.
+let g:ale_linter_aliases = {'vue': ['vue', 'javascript']}
