+## News
+8.22 We upload [R1-Router-3B](https://huggingface.co/hmhm1229/R1-Router-3B).
+
+## Environment
+For training, answer generation, and evaluation processes:
+```bash
+conda create -n router python=3.11
+conda activate router
+pip install requirements_router.txt
+```
+For retriever and corpus construction processes:
+```bash
+conda create -n retriever python=3.11
+conda activate retriever
+pip install requirements_retriever.txt
+```
+
+## Corpora Construction
+For the text corpus, you can download `enwiki-20241020` from [Huggingface](https://huggingface.co/datasets/hmhm1229/enwiki-20241020). Then preprocess, and index it with the following commands:
+```bash
+7z x enwiki-20241020-pages-articles-multistream.xml.zip.001 
+conda activate retriever
+wikiextractor enwiki-20241020-pages-articles-multistream.xml.bz2 -o wiki_extracted
+python wiki_preprocess.py
+```
+For the image corpus, you can directly download [M-BEIR](https://huggingface.co/datasets/TIGER-Lab/M-BEIR). To embed and index it you can follow the [repository](https://github.com/TIGER-AI-Lab/UniIR)
+
+For the table corpus, you can download, embed and index Open-WikiTable following the [repository](https://github.com/sean0042/Open_WikiTable), or you can download directly the one we have already preprocessed from [here](https://huggingface.co/hmhm1229/table-retriever). 
+
+## Retrievers Preparation
+For the Text-Image Retriever, you can directly download [UniIR](https://huggingface.co/TIGER-Lab/UniIR)
+
+For the Table Retriever, you can train it with the help of [repository](https://github.com/sean0042/Open_WikiTable), or you can download it directly from [here](https://huggingface.co/hmhm1229/table-retriever). 
+
+## Datasets
+We have prepared all the text datasets in `./datasets`, for images you need to download them from:
+- `InfoSeek:` InfoSeek images can be downloaded from [OVEN](https://github.com/open-vision-language/oven/tree/main/image_downloads)
+- `Dyn-VQA:` Dynamic VQA images can be downloaded from [DynVQA_en.202412](https://github.com/Alibaba-NLP/OmniSearch/blob/main/dataset/DynVQA_en/DynVQA_en.202412.jsonl)
+- `WebQA:` WebQA images can be downloaded from [Google Drive](https://drive.google.com/drive/folders/19ApkbD5w0I5sV1IeQ9EofJRyAjKnA7tb)
+
+## Training
+If you do not want to train the model, you can download [R1-Router](https://huggingface.co/hmhm1229/R1-Router) and skip this section to [Evaluation](#evaluation)
+### Data Synthesis
+If you want to use the ready-to-use synthetic data directly, you can skip this section to [Step-GRPO Training](#step-grpo-training)
+
+First, we need to synthesis the data step by step:
+```bash
+bash src/data_synthesis/data_synthesis.sh
+```
+### Step-GRPO Training
+Our training framework is based on [EasyR1](https://github.com/hiyouga/EasyR1), only you need to do is to download it and replace some files with the files in `./Easy-R1`.
+Then start training with the command:
+```bash
+conda activate router
+bash examples/run_qwen2_5_vl_7b_stepgrpo.sh
+```
+## Evaluation
+We provide the evaluation pipeline for the R1-Router:
+```bash
+bash evaluation.sh
+```
+or, you can just evaluate the results we have provided by:
+```bash
+conda activate router
+cd src
+python evaluate.py --dataset_name all --method "r1-router3"
+```
+
