+## Highlights
+
+- Beautiful output.
+- Zero-config, but [configurable when needed](#config).
+- Enforces readable code, because you read more code than you write.
+- No need to specify file paths to lint as it lints all JS files except for [commonly ignored paths](#ignores).
+- [Config overrides per files/globs.](#config-overrides) *(ESLint doesn't support this)*
+- Includes many useful ESLint plugins, like [`unicorn`](https://github.com/sindresorhus/eslint-plugin-unicorn), [`import`](https://github.com/benmosher/eslint-plugin-import), [`ava`](https://github.com/avajs/eslint-plugin-ava), and more.
+- Super simple to add XO to a project with `$ xo --init`.
+- Fix many issues automagically with `$ xo --fix`.
+- Open all files with errors at the correct line in your editor with `$ xo --open`.
+- Specify [indent](#indent) and [semicolon](#semicolon) preferences easily without messing with the rule config.
+- Great [editor plugins](#editor-plugins).
