 # Usage examples
 
-## Getting the container
+Two step from zero-to-hero:
+
+1. Download some test content
+2. Transcode with a pre-built container
+
+## Download content
+
+The following will download the Blender TearsOfSteel video:
+
+```bash
+mkdir $(pwd)media
+wget -O $(pwd)/media/TearsOfSteel.mp4 \
+  http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/TearsOfSteel.mp4
+```
+
+## Transcode with a pre-built container
+
+The following will transcode 'TearsOfSteal.mp4' from AVC (H.264) to a 
+5Mbps HEVC (H.265) stream using the GPU.
+
+```bash
+docker run \
+  --device=/dev/dri \
+  --volume $(pwd)/media:/media \
+  amr-registry.caas.intel.com/vtt-osgc/solutions/intel-media-ffmpeg:ubuntu-eoan \
+  ffmpeg \
+    -hwaccel qsv \
+    -qsv_device ${QSV_DEVICE:-/dev/dri/renderD128} \
+    -c:v h264_qsv \
+    -i /media/TearsOfSteel.mp4" \
+    -c:v hevc_qsv \
+    -b:v 5M \
+    -y \
+    /media/TearsOfSteel-5M.mp4
+```
+
+# Getting the container
 
 You can get the intel-media-ffmpeg container by either building it 
 yourself from the Dockerfile, or by pulling a pre-built image from 
 Intel's Harbor instance.
