+## Build Standalone Sample App using makefile.
+
+Hello-QIM is the sample application that can be used to experience the capabilities of the Qualcomm
+Linux platform. The sample application is hosted on GitHub.
+
+Prerequisites:
+Before you begin developing the Hello QIM sample application, ensure that you [Generate platform
+SDK](https://github.com/quic/sample-apps-for-qualcomm-linux) on the host machine.
+
+1. Run the following command to create the platform SDK if not already generated:
+bitbake -c populate_sdk_ext qcom-multimedia-image
+For example:
+/local/mnt/workspace/qcom-6.6.13-QLI.1.0-Ver.1.2_qim-product-sdk/build-qcom-wayland$ bitbake -c populate_sdk_ext qcom-multimedia-image
+The platform SDK is created at <WORKSPACE_DIR>/build-qcom-wayland/tmp-glibc/deploy/sdk/. 
+It is a standalone installer that can be shared with developers interest.
+
+2. Run the following command to extract the platform eSDK:
+Create directory and do the following to install platform eSDK,
+/# sh /local/mnt/workspace/qcom-6.6.13-QLI.1.0-Ver.1.2_qim-product-sdk/build-qcom-wayland/tmp-glibc/deploy/sdk/qcom-wayland-x86_64-qcom-multimedia-image-armv8-2a-qcm6490-toolchain-ext-1.0.sh
+The host is ready for application development. Next, you can develop your first application using the
+platform eSDK.
+
+2. Run the following command to go to the directory where the platform SDK was installed.
+cd <installation directory of platfom SDK>
+3. Run the following command to set up the source environment:
+   source environment-setup-armv8-2a-qcom-linux
+
+4. git clone https://github.com/quic/sample-apps-for-qualcomm-linux
+5. cd sample-apps-for-qualcomm-linux/Hello-QIM 
+6. export SDKTARGETSYSROOT=<path to installation directory of platfom SDK>/tmp/sysroots
+   Example : export SDKTARGETSYSROOT=/local/mnt/workspace/Platform_eSDK_plus_QIM/tmp/sysroots
+
+   export GST_APP_NAME=<appname> 
+   Example: export GST_APP_NAME=gst-appsink
+7. make 
+
+To run the Hello-QIM program, do the following
+
+8. Run the following command to transfer the program to the Qualcomm Reference kit.
+adb push gst-appsink /opt/
+adb shell chmod 777 /opt/gst-appsink
+cd /opt/
+./gst-appsink -w 1280 -h 720.
+
+The Hello-QIM application is successfully created. The following message is displayed:
+Hello-QIM: Success creating pipeline and received camera frame.
