+Markdown Widget for Yii 2
+=========
+Widget based on [simplemde-markdown-editor](https://github.com/NextStepWebs/simplemde-markdown-editor) 
+
+Installation 
+------------
+
+The preferred way to install this extension is through [composer](http://getcomposer.org/download/).
+
+Either run
+
+```
+php composer.phar require --prefer-dist yii2mod/yii2-markdown "*"
+```
+
+or add
+
+```json
+"yii2mod/yii2-markdown": "*"
+```
+
+to the require section of your composer.json.
+
+Usage
+------------
+Once the extension is installed, simply add widget to your page as follows:
+
+1) Usage with ActiveForm and model
+```php
+<?php echo $form->field($model, 'content')->widget(\yii2mod\markdown\MarkdownEditor::class, [
+    'editorOptions' => [
+        'showIcons' => ["code", "table"],
+    ],
+]); ?>
+```
+2) Usage without ActiveForm and model
+```php
+<?php echo \yii2mod\markdown\MarkdownEditor::widget([
+    'name' => 'markdown-editor',
+    'editorOptions' => [
+        'showIcons' => ["code", "table"],
+    ],
+]);
+?>
+```
+
