+### Video capture API
 
 The Video capture API is one of the services of ACAP Runtime.
 
 The ACAP Computer Vision solution offers a mechanism for capturing frames using the ACAP Runtime. By sending a gRPC request to the ACAP runtime, users can establish a video stream and retrieve frames.
 
 The Python client is accessible within the ACAP Runtime proto image at `/build/vdo/proto_utils` and is imported into Python as `VideoCaptureClient`, located within the `vdo_proto_utils` module. This client exposes the `get_frame` function, facilitating frame retrieval and parsing.

+#### The VideoCapture object
 
 To instantiate a VideoCaptureClient object, you need to provide the ACAP runtime communication socket, along with the desired stream dimensions and framerate.
 In some cases, this call could take up to two minutes, if the ACAP runtime is busy doing other tasks like loading a machine learning model on start up.

-### VideoCapture requirements
+#### VideoCapture requirements
 
 For the video capture client to work, it is required that the ACAP runtime is installed and running.
 The application and the ACAP runtime need to share a socket file to allow the gRPC communication.
 To achieve this, a volume needs to be mounted between the application and the ACAP runtime container.

-## Machine learning API
+### Machine learning API
 
 The Machine learning API is one of the services of ACAP Runtime.
 
 The ACAP Computer Vision solution provides a flexible way of allowing machine learning inference in the form of TensorFlow Serving and a TensorFlow Serving client. TensorFlow Serving allows for making inference calls over gRPC to another container, the inference server, and a model server. This has several benefits, including exposing a common API for inference and having a single process handle all apps DLPU communication.
 
 The Python client is available in the ACAP runtime proto image under `/build/tf/proto_utils` and imported in Python as `InferenceClient`, which is available in the `tf_proto_utils` module. The client exposes a single `infer(inputs, model_name)` function that enables an easy inference from the main application that will also be connected to the model server.
