+## Issues ##
+
+Try to be the most specific possible. Give your OS, Node.js, application, database and packages info.
+Give an example that will help other people to replicate your problem.
+
+
+## Pull Requests ##
+
+They are always welcomed but with respect to the adopted [code style](https://github.com/DarkPark/jscs) and included [ESLint](http://eslint.org/) rules.
+Your patches must pass all the tests. If adding a new feature, don't forget about adding it to documentation (readme.md) and add tests for it.

+Tasks generator for ESLint
+==========================
+

+[![dependencies status](https://img.shields.io/david/runner/generator-eslint.svg?style=flat-square)](https://david-dm.org/runner/generator-eslint)

+[![RunKit](https://img.shields.io/badge/RunKit-try-yellow.svg?style=flat-square)](https://npm.runkit.com/@runner/generator-eslint)
+
+
+## Installation ##
+
+```bash
+npm install @runner/generator-eslint
+```
+
+
+## Usage ##
+
+Add to the scope:
+
+```js
+var generator = require('@runner/generator-eslint');
+```
+
+Add generated tasks to the runner instance:
+
+```js
+var runner = require('@runner/core');
+
+runner.tasks(
+    generator({
+        watch: ['src/js/**/*.js']
+    })
+);
+```
+
+The following tasks will become available:
+
+ Task name      | Description
+----------------|-------------
+ eslint:config  | prints the current configuration used for generated tasks
+ eslint:watch   | starts file changes monitoring, prints warnings on errors
+ eslint:unwatch | stops monitoring
+
+Generator configuration object:
+
+ Name         | Description
+--------------|-------------
+ watch        | file, dir, glob, or array passed to `watch` in [chokidar](https://www.npmjs.com/package/chokidar#api)
+ watchOptions | optional watcher config object [parameters](https://www.npmjs.com/package/chokidar#api)
+ options      | optional config object passed to [ESLint CLIEngine](https://eslint.org/docs/developer-guide/nodejs-api#cliengine)
+
+Additional generator options:
+
+ Name   | Description
+--------|-------------
+ prefix | an affix placed before a task name (default is `eslint:`)  
+ suffix | a string added at the end of a task name (empty by default)
+
+So it's possible to change generated tasks names: 
+
+```js
+runner.tasks(
+    generator(config, {
+        prefix: 'lint:',
+        suffix: ':develop'
+    })
+);
+```
+
+This will create the following tasks:
+
+* lint:config:develop  
+* lint:watch:develop   
+* lint:unwatch:develop 
+
