+# Convert a Megatron torch_dist checkpoint to HuggingFace format.
+#
+# Required env vars:
+#   MEGATRON_CKPT_DIR  - path to the Megatron checkpoint directory (e.g., /root/models/<name>_ckpt__<config>/iter_0000150)
+#   HF_OUTPUT_DIR      - path to save the converted HuggingFace model
+#   ORIGIN_HF_DIR      - path to the original HuggingFace model (for config.json, tokenizer, etc.)
+#
+# Example:
+#   MEGATRON_CKPT_DIR=/root/models/Qwen3-4B-Base-sft_ckpt__qwen3-4b-lightning-opd/iter_0000150 \
+#   HF_OUTPUT_DIR=checkpoints/qwen3-4b-lightning-opd-hf \
