 > Automated User Guide Generation with Markdown
 
+GuideAutomator allows developers and technical writers to create user manuals with screenshots that are always in sync with the latest version of the application being documented. For that end, it takes as input a Markdown file containing the user manual text with short JavaScript chunks that determine how to capture each screencast.
+
+Sample GuideAutomator input:
+
+    ## How to find GuideAutomator
+
+    Open the Bing website and type `GuideAutomator aside-ufba`:
+
+    ```javascript
+    get('https://bing.com/');
+    fillIn('#sb_form_q', 'GuideAutomator aside-ufba');
+    takeScreenshotOf('#sb_form>div', true);
+    ```
+
+    Press *Enter*. The first result should be what you are looking for:
+
+    ```javascript
+    submit('#sb_form');
+    takeScreenshotOf('#b_results>li:nth-child(1)', true);
+    ```
