C/C++ Sample Apps Source Details
====================================
The DeepStream SDK package includes archives containing plugins, libraries, applications, and source code.
The sources directory is located at ``/opt/nvidia/deepstream/deepstream-6.0/sources`` for both Debian installation (on Jetson or dGPU) and SDK Manager installation. For tar packages the source files are in the extracted `deepstream` package.
DeepStream Python bindings and sample applications are available as separate packages. For more information, see https://github.com/NVIDIA-AI-IOT/deepstream_python_apps.

DeepStream graphs created using the Graph Composer are listed under :doc:`DS_Zero_Coding_Sample_Graphs` section. For more information, see the Graph Composer :doc:`DS_Zero_Coding_Introduction`.
