+# mrm-task-xo
+
+[![Build Status](https://travis-ci.org/bdougherty/mrm-task-xo.svg)](https://travis-ci.org/bdougherty/mrm-task-xo)
+
+> [Mrm](https://github.com/sapegin/mrm) task that adds [xo](https://github.com/sindresorhus/xo).
+
+## What it does
+
+* Updates the npm test script to run xo
+* Adds specified configuration to `package.json`
+* Installs xo
+
+## Usage
+
+```
+mrm xo
+mrm xo --config:xoExtends=bdougherty --config:xoExtends=foo
+```
+
+## Options
+
+### `xoSpace` (optional, default: `false`)
+
+Set it to `true` to get 2-space indentation or specify the number of spaces.
+
+This option is set automatically if you have the `indent` option set in your [mrm config](https://github.com/sapegin/mrm#configuration).
+
+This option exists for pragmatic reasons, but I would strongly recommend you read [“Why tabs are superior”](http://lea.verou.me/2012/01/why-tabs-are-clearly-superior/).
+
+### `xoSemicolon` (optional, default: `true`)
+
+Set it to `false` to enforce no-semicolon style.
+
+### `xoPlugins` (optional)
+
+Include third-party [plugins](https://eslint.org/docs/user-guide/configuring.html#configuring-plugins).
+
+### `xoExtends` (optional)
+
+Use one or more [shareable configs](https://eslint.org/docs/developer-guide/shareable-configs.html) or [plugin configs](https://eslint.org/docs/user-guide/configuring#using-the-configuration-from-a-plugin) to override any of the default rules.
