+## Building Docker Images
+
+To build the manylinux Docker images for different architectures:
+
+```bash
+# Build x86_64 images (default)
+./deploy.bash
+
+# Build ARM64/aarch64 images
+./deploy.bash --arch aarch64
+
+# Build and push images with version tag
+./deploy.bash --version 2025.1 --push
+
+# Build, tag as latest, and push
+./deploy.bash --version 2025.1 --push --latest
