+## Build release packages
+
+Release packages include heron.tar.gz as well as installer script. Packages are platform dependent.
+
+Example:
+
+```bash
+set -e
+set -o pipefail
+
+# Install bazel (linux build) because CI hosts may not have it installed
+sh scripts/ci/setup_bazel.sh linux
+
+# Build v0.20.1-incubating packages for centos7 and put in artifacts folder
+HERON_BUILD_USER=release-agent
+sh scripts/ci/build_release_packages.sh v0.20.1-incubating centos7 artifacts
+
+```
+
+## Build maven artifacts
+
+Maven argifacts include api, spi, storm-compatibility and simulator. Artifacts are platform indepedent.
+
+Example:
+
+```bash
+set -e
+set -o pipefail
+
+# Build v0.20.1-incubating artifacts and put in artifacts folder
+HERON_BUILD_USER=release-agent
+sh scripts/ci/build_maven_artifacts.sh v0.20.1-incubating artifacts
