+=========================
+
+This linter plugin for [Linter](https://github.com/AtomLinter/Linter) provides an interface to [markdownlint](https://github.com/mivok/markdownlint). It will be used with files that have the “Markdown” syntax.
+
+## Installation
+Linter package must be installed in order to use this plugin. If Linter is not installed, please follow the instructions [here](https://github.com/AtomLinter/Linter).
+
+### mdl installation
+Before using this plugin, you must ensure that `mdl` is installed on your system. To install `mdl`, do the following:
+
+1. Install [ruby](https://www.ruby-lang.org/).
+
+2. Install [markdownlint](https://github.com/mivok/markdownlint) by typing the following in a terminal:
+   ```
+   gem install mdl
+   ```
+
+Now you can proceed to install the linter-markdownlint plugin.
+
+### Plugin installation
+```
+$ apm install linter-markdownlint
+```
+
+## Settings
+You can configure linter-markdownlint by editing ~/.atom/config.cson (choose Open Your Config in Atom menu):
+
+```
+'linter-markdownlint':
+  'executableDir': null # markdownlint directory path.
+  'binaryName': mdl # mdl binary name.
+```
+Run `which mdl` to find the path,
+if you using rbenv run `rbenv which mdl`
