-## Download
+This repository contains the versioned road-network bundle used by [VehicleArena](https://github.com/OpenMOSS/VehicleArena). The simulator, benchmark scenarios, evaluation code, and map installer live in the GitHub repository; the large offline maps are distributed here.
+
+**Start here:** [Download](#-download) · [Install](#-installation) · [Benchmark context](#-benchmark-context) · [Citation](#-citation)
+
+## 🌟 Highlights
+
+- **116 road-network maps:** the archive contains 116 base road networks and their 116 lane-level counterparts, for 232 map JSON files in total.
+- **Versioned and verifiable:** the archive follows CalVer `YYYY.MM.DD.PATCH`; the VehicleArena installer checks its SHA-256 and the individual map files against the code repository's manifest.
+- **Maps, not trajectories:** task definitions and evaluation software are maintained on GitHub, so the same map bundle can be used with the published tasks or new scenarios.

+The archive can also be downloaded with the Hugging Face CLI:
+
+```bash
+hf download OpenMOSS-Team/VehicleArena \
+  vehiclearena-road-networks-2026.09.22.0.tar.gz \
+  --repo-type dataset --local-dir /path/to/downloads
+```
+
+## 🚀 Installation
+
+First set up the [VehicleArena code and dependencies](https://github.com/OpenMOSS/VehicleArena#-quick-start). From the code repository root, install the downloaded archive and check the environment:
+
 ```bash
-hf download OpenMOSS-Team/VehicleArena vehiclearena-road-networks-2026.09.22.0.tar.gz --repo-type dataset --local-dir /path/to/downloads
+python scripts/manage_map_bundle.py install \
+  --source /path/to/downloads/vehiclearena-road-networks-2026.09.22.0.tar.gz
+python scripts/check_environment.py
 ```
 
-## Install
+The check reports `"ready": true` when Python, SUMO, and the maps are available. See the [map installation guide](https://github.com/OpenMOSS/VehicleArena/blob/main/vehiclearena/simulation/MAPS.md) for the archive layout and checksum validation.
+
+## 📊 Benchmark context
 
-Follow the [map installation guide](https://github.com/OpenMOSS/VehicleArena/blob/main/vehiclearena/simulation/MAPS.md). The installer checks the archive and each map file against the manifest tracked in the code repository.
+The published VehicleArena benchmark has 100 training/development tasks and 112 held-out evaluation tasks: 80 Basic and 32 MultiLLM. Those tasks, their manifests, and the evaluation code are in [GitHub](https://github.com/OpenMOSS/VehicleArena), not in this map archive. The published time limits were calibrated using this map version; changing road data or task definitions requires recalibrating affected scenarios. Reusing the same archive with another evaluated model does not.
 
-The map bundle contains road-network assets, not driving trajectories. VehicleArena's task definitions and evaluation instructions are maintained in the [GitHub code repository](https://github.com/OpenMOSS/VehicleArena).
