+# Body Pose Invocation asynchronous invocation
+
+This example uses the pre-trained classification model by DEEP-Hybrid-DataCloud
+[Body Pose Detection](https://marketplace.deep-hybrid-datacloud.eu/modules/deep-oc-posenet-tf.html)
+and is prepared to be used with asynchronous invocations.
+
+
+In order to invoke the function, first you have to do is create a service,
+either by the OSCAR UI or by using the FLD within the following command.
+
+``` sh
+oscar-cli apply body-pose-detection-async.yaml
+```
+
+Once the service is created you can make the invocation with the following
+command, which will store the output on a minio bucket.
+
+``` sh
+oscar-cli service put-file body-pose-detection-async minio images/001.jpg body-pose-detection-async/input/001.jpg
+```
