+Grab via Gradle:
 
 ```gradle
- dependencies {
-   compile 'is.handsome.pixelperfect:pixelperfect:0.1'
- }
+compile 'is.handsome.pixelperfect:pixelperfect:1.0.1'
+```
+

+
+```maven
+<dependency>
+<groupId>is.handsome.pixelperfect</groupId>

+<version>1.0.1</version>
+<type>pom</type>
+</dependency>
 ```
+
+## Getting started
+
+#### Show PixelPerfect
+```java
+PixelPerfect.show(HomeActivity.this);
+```
+
+In default configuration PixelPerfect will be linked with 'pixelperfect' assets folder.
+
+![Assets](https://s3.amazonaws.com/f.cl.ly/items/3m231E1W312M0U0X2t3U/assets.png?v=630e4d1b "Assets")
+
+If you want to use different folder, please read `Configuration` section.
+
+#### Hide PixelPerfect
+```java
+PixelPerfect.hide();
+```
+
+## Configuration
+
+`PixelPerfect.Config` provides possibility to configure major attributes of PixelPerfect. This snippet demonstrates usage of custom `overlayImagesAssetsPath` (assets folder for overlay images) and `overlayActiveImageName` (name of active by default overlay image):
+
+```java
+PixelPerfect.Config config = new PixelPerfect.Config.Builder()
+.overlayImagesAssetsPath("my_overlays")
+.overlayActiveImageName("main.png")
+.build();
+PixelPerfect.show(HomeActivity.this, config);
+```
+
+## Permissions and Android Marshmallow+
+
+PixelPerfect requires SYSTEM_ALERT_WINDOW permission to run properly. So, for Marshmallow and later versions you have to handle permissions with `PixelPerfect.hasPermission(context)` and `PixelPerfect.askForPermission(context)` methods.
+
+You can find demonstartion of its usage in Sample app.
