 ## 2.1 Set up HISPlayer Manager
-Create a script (for example **iOSStreamController**) which is going to inherit from **HISPlayerManager**. It is needed to include the namespace by adding **‘using HISPlayerAPI;’** and add this component to a GameObject. It is recommended to create an **Empty GameObject** for this.

+Remember to call the Release function after closing the app or before changing scenes in Unity for freeing the internal resources.

 ### <ins>RenderTexture</ins>
-First of all, check if the Resources folder exists and contains the RenderTextures folder. If it doesn’t exist then create it from zero. In this case, look for the Resources folder and copy its contents into the Unity Assets folder. This folder contains Unity RenderTexture resources. Another option is creating RenderTexture in Assets directly.
+For this you can use the RenderTexture we provide or create a RenderTexture from zero. In the first case, go to the Resources folder of our package and attach the **Resources > Materials > HISPlayerDefaultMaterialRenderTexture.mat** to the GameObject that is going to be used as screen and the **Resources > RenderTextures > HISPlayerRenderTexture.renderTexture** to the stream controller component.
 
-The **RenderTexture** has to be attached to the GameObject which will be a screen for rendering the multimedia stream.
+For creating it from zero, select **Assets > Create > Render Texutre** and then create a **Material** referencing the **Render Texture**. This last action can be done automatically by grabbing the **Render Texture** and dropping it at the end of a GameObject's Inspector with the component **Mesh Renderer** with **Material field empty**. This will create the new material inside a **Materials** folder. 
 
-For creating this object, select **GameObject > 3D Object > Quad**. Then select the GameObject and remove the material attached to its **Mesh Renderer** component, then replace it with the **RenderTexture** created. The **RenderTextures** folder provided by the SDK contains the **Material** folder and this material is the one which is needed to be used for the replacement . If the **RenderTexture** resource has been created from 0, then another option is to grab the **RenderTexture** from the **Assets** folder and drop it at the end of the GameObject’s Inspector, this will create a new material automatically.
+Once all this process it’s done, associate the **RenderTexture** to the script component.
