+Images are output to `build/` directory.
+
+## Upload to GitHub Container Registry
+
+```bash
+# Login to ghcr.io
+# Provision a token with write packages permissions
+echo "GH_TOKEN" | docker login ghcr.io -u <username> --password-stdin
+
+# Load and tag images
+docker load -i build/cli-amd64.tar
+docker load -i build/cli-arm64.tar
+
+# Tag for registry
+docker tag databricks-cli:amd64 ghcr.io/databricks/cli:latest-tf-amd64
+docker tag databricks-cli:arm64 ghcr.io/databricks/cli:latest-tf-arm64
