+# eslint-plugin-import-grouped
+
+Import statements should be grouped by extensions and groups can have custom order between them
+
+## Installation
+
+You'll first need to install [ESLint](http://eslint.org):
+
+```
+$ npm i eslint --save-dev
+```
+
+Next, install `eslint-plugin-import-grouped`:
+
+```
+$ npm install eslint-plugin-import-grouped --save-dev
+```
+
+**Note:** If you installed ESLint globally (using the `-g` flag) then you must also install `eslint-plugin-import-grouped` globally.
+
+## Usage
+
+Add `import-grouped` to the plugins section of your `.eslintrc` configuration file. You can omit the `eslint-plugin-` prefix:
+
+```json
+{
+    "plugins": [
+        "import-grouped"
+    ]
+}
+```
+
+
+Then configure the rules you want to use under the rules section.
+
+```json
+{
+    "rules": {
+        "import-grouped/rule-name": 2
+    }
+}
+```
+
+## Supported Rules
