+This directory includes scripts to build the docker container image used for
+building flutter/engine in our CI system (currently [Cirrus](cirrus-ci.org)).
+
+In order to run the scripts, you have to setup `docker` and `gcloud`. Please
+refer to the [internal flutter team doc](go/flutter-team) for how to setup in a
+Google internal environment.
+
+After setup,
+* edit `Dockerfile` to change how the container image is built.
+* run `./build_docker.sh` to build the container image.
+* run `./push_docker.sh` to push the image to google cloud registry. This will
+  affect our CI tests.
