-We can only process bug reports that are actionable. Unclear bug reports or
-reports with insufficient information may not get attention.
-
-Before filing a bug:
--------------------------
-
-- Search existing issues, including issues that are closed:
-  https://github.com/androidx/media/issues?q=is%3Aissue
-- For ExoPlayer-related bugs, please also check the ExoPlayer tracker:
-  https://github.com/google/ExoPlayer/issues?q=is%3Aissue
-
-When reporting a bug:
--------------------------
-
-Describe how the issue can be reproduced, ideally using one of the demo apps
-or a small sample app that you’re able to share as source code on GitHub. To
-increase the chance of your issue getting attention, please also include:
-
-- Clear reproduction steps including observed and expected behavior
-- Output of running "adb bugreport" in the console shortly after encountering
-  the issue
-- URI to test content for reproduction
-- For protected content:
-  - DRM scheme and license server URL
-  - Authentication HTTP headers
-
-- AndroidX Media version number
-- Android version
-- Android device
-
-If there's something you don't want to post publicly, please submit the issue,
-then email the link/bug report to dev.exoplayer@gmail.com using a subject in the
-format "Issue #1234", where #1234 is your issue number (we don't reply to
-emails).

+## MediaPipe frame processing demo
+
+Building the demo app with [MediaPipe][] integration enabled requires some extra
+manual steps.
+
+1.  Follow the
+    [instructions](https://google.github.io/mediapipe/getting_started/install.html)
+    to install MediaPipe.
+1.  Copy the Transformer demo's build configuration and MediaPipe graph text
+    protocol buffer under the MediaPipe source tree. This makes it easy to
+    [build an AAR][] with bazel by reusing MediaPipe's workspace.
+
+    ```sh
+    cd "<path to MediaPipe checkout>"
+    MEDIAPIPE_ROOT="$(pwd)"
+    MEDIAPIPE_TRANSFORMER_ROOT="${MEDIAPIPE_ROOT}/mediapipe/java/com/google/mediapipe/transformer"
+    cd "<path to the transformer demo (containing this readme)>"
+    TRANSFORMER_DEMO_ROOT="$(pwd)"
+    mkdir -p "${MEDIAPIPE_TRANSFORMER_ROOT}"
+    mkdir -p "${TRANSFORMER_DEMO_ROOT}/libs"
+    cp ${TRANSFORMER_DEMO_ROOT}/BUILD.bazel ${MEDIAPIPE_TRANSFORMER_ROOT}/BUILD
+    cp ${TRANSFORMER_DEMO_ROOT}/src/withMediaPipe/assets/edge_detector_mediapipe_graph.pbtxt \
+      ${MEDIAPIPE_TRANSFORMER_ROOT}
+    ```
+
+1.  Build the AAR and the binary proto for the demo's MediaPipe graph, then copy
+    them to Transformer.
+
+    ```sh
+    cd ${MEDIAPIPE_ROOT}
+    bazel build -c opt --strip=ALWAYS \
+      --host_crosstool_top=@bazel_tools//tools/cpp:toolchain \
+      --fat_apk_cpu=arm64-v8a,armeabi-v7a \

+      --copt=-DABSL_MIN_LOG_LEVEL=2 \
+      --linkopt=-Wl,--gc-sections,--strip-all \
+      mediapipe/java/com/google/mediapipe/transformer:edge_detector_mediapipe_aar.aar
+    cp bazel-bin/mediapipe/java/com/google/mediapipe/transformer/edge_detector_mediapipe_aar.aar \
+      ${TRANSFORMER_DEMO_ROOT}/libs
+    bazel build mediapipe/java/com/google/mediapipe/transformer:edge_detector_binary_graph
+    cp bazel-bin/mediapipe/java/com/google/mediapipe/transformer/edge_detector_mediapipe_graph.binarypb \
+      ${TRANSFORMER_DEMO_ROOT}/src/withMediaPipe/assets
+    ```
+
+1.  In Android Studio, gradle sync and select the `withMediaPipe` build variant
+    (this will only appear if the AAR is present), then build and run the demo
+    app and select a MediaPipe-based effect.
