 This project hosts a container demonstrating the use of ffmpeg
 using GPU offload for transcode operations.
 
+The Dockerfile itself is constructed from templates/* and Dockerfile.solution,
+and provides a multi-stage Docker container with the final container
+being a minimal run-time installation on top of the base OS.
+
 # Usage examples
 
-## Build the container
+## Getting the container
 
-Build the container:
-
-```bash
-docker build . -t intel-media-ffmpeg
-```
-
-or you can pull the container from Harbor:
+You can pull the container from Harbor:
 
 ```bash
 docker pull amr-registry.caas.intel.com/vtt-osgc/solutions/intel-media-ffmpeg
 docker tag amr-registry.caas.intel.com/vtt-osgc/solutions/intel-media-ffmpeg intel-media-ffmpeg
 ```
 
-
-## Download test content
-
-You will need some test content to run the following tests. You can download a
-test stream here:
+or build it yourself:
 
 ```bash
-[ ! -e media ] && mkdir media
-wget -q -O media/AUD_MW_E.264 https://fate-suite.libav.org/h264-conformance/AUD_MW_E.264
+docker build . -t intel-media-ffmpeg
 ```
 
-## Run a set of tests in sequence
+## Verify hardware access
 
-The following will decode, encode, and transcode the sample content:
 ```bash
-HOST_MEDIA=$(pwd)/media
-[ ! -e "${HOST_MEDIA}/AUD_MW_E.264" ] && {
-  mkdir -p ${HOST_MEDIA}
-  wget -q -O ${HOST_MEDIA}/AUD_MW_E.264 https://fate-suite.libav.org/h264-conformance/AUD_MW_E.264
-}
-tests=(
-  "decode AUD_MW_E.264 AUD_MW.yuv"
-  "encode AUD_MW.yuv AUD_MW_E.h264"
-  "transcode AUD_MW_E.264 AUD_MW_E.hevc"
-  "1N_transcode AUD_MW_E.264 AUD_1N"
-)
-for test in "${tests[@]}"; do
-  test=($test)
-  docker run --rm \
-    --volume ${HOST_MEDIA}:/media -it \
-    --device=/dev/dri -e QSV_DEVICE=${QSV_DEVICE:-/dev/dri/renderD128} \
-      intel-media-ffmpeg ${test[*]} || {
-    echo "Error: Test failed: ${test[*]}"
-    break
-  }
-done
+docker run \
+  --rm \
+  --device=/dev/dri \
+  -e QSV_DEVICE=${QSV_DEVICE:-/dev/dri/renderD128} \
+  -it \
+  intel-media-ffmpeg \
+  info
 ```
 
-If successful, looking in ${HOST_MEDIA} should show the following files:
+The above will provide information about the software
+in the container, as well as the detected Intel graphics
+hardware.
+
+If you are in a multicard environment, see Appendix A.
+
+## Test hardware accelerated FFMPEG media operations
 
 ```bash
-$ ls -1tr "${HOST_MEDIA}"
+scripts/test
+```
+
+The above will:
+
+1. Download a test content file from fate-suite.libav.org into $(pwd)/media
+2. Instantiate the 'intel-media-ffmpeg' container
+3. Perfom the following tests:
+  1. decode AUD_MW_E.264 to AUD_MW.yuv
+  2. encode AUD_MW.yuv to AUD_MW_E.h264
+  3. transcode AUD_MW_E.264 to AUD_MW_E.hevc
+  4. transcode AUD_MW_E.264 to two streams at once, AUD_1N-5M.h264 and AUD_1N-4M60FPS.h264
+
+Once completed, you can check the contents of $(pwd)/media for the following files:
+
+```
 AUD_MW_E.264
 AUD_MW.yuv
 AUD_MW_E.h264
 AUD_MW_E.hevc
-AUD_1N-5M.mp4
+AUD_1N-5M.h264
 AUD_1N-4M60FPS.h264
 ```
