+# Velox Backend CI
+
+GHA workflows are defined under `.github/workflows/`.
+
+## Docker Build
+We have a weekly job to build a docker based on `Dockerfile.gha` for CI verification, defined in `docker_image.yml`.
+
+## Vcpkg Caching
+Gluten main branch is pulled down during docker build. And vcpkg will cache binary data of all dependencies defined under dev/vcpkg.
+These binary data is cached into `/var/cache/vcpkg` and CI job can re-use them in new build. By setting `VCPKG_BINARY_SOURCES=clear` in env.,
+reusing vcpkg cache can be disabled.
+
+## Arrow Libs Pre-installation
+Arrow libs are pre-installed in docker, assuming they are not actively changed, then not necessarily to be re-built every time.
+
+## Updating Docker Image
+Two GitHub secrets `DOCKERHUB_USER` & `DOCKERHUB_TOKEN` can be used to push docker image to docker hub: https://hub.docker.com/r/apache/gluten/tags.
+Note GitHub secrets are not retrievable in PR from forked repo.
