+## Introduction
+
+**ORBIT: A Unified Toolbox for LLM Routing** is a modular, extensible open-source toolbox for **large language model (LLM) routing**, also known as **model routing**. It studies how to select the most suitable model from a heterogeneous model pool **for each query**, under practical deployment constraints such as **cost, latency, and throughput**.
+
+ORBIT unifies LLM router development, cost-aware inference, text-only and multimodal routing benchmarks, and reproducible performance-cost evaluation. The repository name and URL remain **ORBIT** to preserve existing paper and project links.

 LLM routing methods are rapidly emerging, but existing implementations are often fragmented: they use different benchmark splits, cost assumptions, evaluation scripts, and router interfaces. This makes fair comparison and reproducibility difficult.

+### Project naming
+
+Use **ORBIT: A Unified Toolbox for LLM Routing** on first mention in future papers,
+project introductions, and documentation for related open-source routing methods;
+use **ORBIT** thereafter. Link to the canonical repository,
+[LAMDA-Model-Reuse/ORBIT](https://github.com/LAMDA-Model-Reuse/ORBIT), without renaming it.
+When citing the published FCS paper, retain its original bibliographic title,
+**ORBIT: An Optimal Routing and Budgeted Inference Toolbox**, and DOI as listed below.
+
+### Pull request checklist
+
+Before submitting a PR, please try to include:
 
 - A concise description of the method, dataset, or utility being added.
 - Configuration files needed to reproduce the experiment.
