+
+## Quick start
+
+From the ANWM code repo root:
+
+```bash
+# download into the path expected by infer.py / check_environment.py
+huggingface-cli download EmbodiedCity/ANWM \
+  logs/anwm_cdit_airvln/checkpoints/0200000.pth.tar \
+  --local-dir .
+
+# optional check
+python scripts/check_environment.py --require-checkpoint
+
+# inference
+torchrun --standalone --nproc_per_node=1 infer.py \
+  --exp config/anwm.yaml \
+  --ckp 0200000 \
+  --datasets airvln_16 \
+  --eval_type rollout \
+  --rollout_fps_values 1,4
+```
+
+The downloaded layout matches the documented local path:
