 ### Usage
 
 * Once installed, we can see the **MCOP SDK** installed on our device in the application list.
 
 * The SDK comes built in with a raw interface Test Client *(see the screenshots section below)*.
 
 * For a full user experience, we recommend checking out our [**MCOP MCPTT Client**](https://demo.mcopenplatform.org/gitlist/mcop/MCOP-MCPTT-Client.git/blob/master/docs/MCOP_MCPTT_Client_Installation.md), with a full GUI interface.
 

 * Every time the [**MCOP MCPTT Client**](https://demo.mcopenplatform.org/gitlist/mcop/MCOP-MCPTT-Client.git/blob/master/README.md) *(or the mentioned built in Test Client)* is started, it uses the configuration selected in the [**Provisioning App**](Provisioning.md).

 * **IMPORTANT**: In order to test the Test Client against our [demo.mcopenplatform.org](https://demo.mcopenplatform.org) testing platform, the user configuration settings provided by email when booking a testing slot need to be updated in the [Provisioning App](https://demo.mcopenplatform.org/gitlist/mcop/MCOP-SDK.git/raw/master/provisioning/MCOP_ProvisioningTool.apk). **Full detailed information is available in [Provisioning Tool](ProvisioningTool.md) documentation**.

 
 * Check [MCOP MCPTT App Development](MCOP_App_developing_steps.md) guide for more info on app development using the MCOP SDK.
