+# Download Artifacts Script
+#
+# This script downloads build artifacts from a GitHub Actions run and processes them
+# for consistent naming. It requires:
+#   - GitHub CLI (gh) to be installed and authenticated
+#   - Two arguments:
+#     1. Target path where artifacts should be downloaded
+#     2. GitHub Actions run ID to download artifacts from
+#
+# Example usage:
+#   ./download-artifacts.sh 2024.10.2 1234567890
+#
+# The script will:
+# 1. Create the target directory if it doesn't exist
+# 2. Download all artifacts from the specified GitHub Actions run
+# 3. Process the artifacts to have consistent naming based on their folders
+# 4. Move artifacts up to the target path
+
+# Check if required arguments are provided
+if [ $# -ne 2 ]; then
+    echo "Usage: $0 <path> <github_run_id>"
+    exit 1
