+## 架构设计
 
-### 数据集特性
-- 支持多语言混合训练（中/英文）
-- 包含以下预训练数据源：
-  - Chinese-C4
-  - Chinese-Cosmopedia
-  - English-Fineweb
-  - English-Wiki
-- 支持监督微调数据集：
-  - Ling-Coder-SFT
-  - Chinese-Instruct
-  - BelleGroup
-  - Magpie-Pro-300K
+本项目采用模块化设计，应用了多种设计模式：
+
+### 设计模式
+1. **策略模式** - 不同类型的数据处理器（PT/SFT/DPO）
+2. **工厂模式** - 处理器工厂统一创建实例
+3. **模板方法模式** - 数据管道流程标准化
+
+### 核心组件
+
+#### DataPipeline（数据管道）
+主数据管道，负责数据集的分块处理、格式转换和存储。
+
+```python
+from modules.datapipeline import DataPipeline
+
+pipeline = DataPipeline(output_dir="./dataset")
+pipeline.process_dataset(
+    dataset_dict=dataset,
+    output_subdir="my-data"
+)
+```
+
+#### ProcessorFactory（处理器工厂）
+创建不同类型的数据处理器。
+
+```python
+from modules.datapipeline import ProcessorFactory
+from modules.tokenizer import BpeTokenizer
+
+tokenizer = BpeTokenizer("tokenizer.json")
+
+# 创建预训练处理器
+processor = ProcessorFactory.create("pt", tokenizer)
+
+# 创建SFT处理器
+processor = ProcessorFactory.create("sft", tokenizer)
+```
+
+#### TextNormalizer（文本规范化）
+文本预处理和规范化。
+
+```python
+from modules.datapipeline import TextNormalizer
+
+normalizer = TextNormalizer()
+normalized_text = normalizer.normalize(text)
+```
+
+## 使用说明
+
+### 安装依赖
 
-### 使用说明
-1. 安装依赖：
 ```bash
-pip install datasets tokenizers tqdm torch
+pip install datasets tokenizers tqdm torch h5py
 ```
-运行数据处理：
+
+### 运行数据处理
+
+运行所有数据处理脚本：
 
 ```bash
 python run.py
+```
+
+运行特定脚本：
+
+```bash
+# 预训练数据处理
+python pre_train/english-wiki.py
+
+# SFT数据处理
+python supervised_finetuning/sft_belle.py
+
+# DPO数据处理
+python reforce_learning/dpp_chinese_dpo_pairs.py
+```
+
+### 自定义数据处理
+
+#### 1. 基础数据处理
+
+```python
+from datasets import load_dataset
+from modules.datapipeline import DataPipeline
+
+# 加载数据集
+dataset = load_dataset("your-dataset")
+
+# 创建管道
+pipeline = DataPipeline()
+
+# 处理数据
+pipeline.process_dataset(
+    dataset_dict=dataset,
+    output_subdir="output-dir",
+    process_func=lambda x: {"text": x["content"]}
+)
+```
+
+#### 2. 自定义处理器
+
+```python
+from modules.datapipeline.processors import BaseProcessor
+from modules.datapipeline import ProcessorFactory
+
+class MyProcessor(BaseProcessor):
+    def __init__(self, tokenizer):
+        self.tokenizer = tokenizer
+    
+    def process(self, input_dict: dict) -> dict:
+        # 自定义处理逻辑
+        return {"processed": data}
+    
+    @property
+    def output_keys(self) -> list:
+        return ["processed"]
+
+# 注册处理器
+ProcessorFactory.register("my_type", MyProcessor)
+```
+
+#### 3. 文本规范化
+
+```python
+from modules.datapipeline import TextNormalizer
+
+# 使用默认规则
+normalizer = TextNormalizer()
+text = normalizer.normalize(text)
+
+# 自定义规则
+custom_rules = {"旧词": "新词"}
+normalizer = TextNormalizer(custom_rules)
+```
+
+## 数据输出格式
+
+### JSONL格式
+每个数据块保存为JSONL文件：
+```
+{"text": "训练文本内容..."}
+{"query": "问题", "response": "答案"}
+```
+
+### H5格式
+打包后的张量数据保存为HDF5格式，支持高效加载：
+```python
+from modules.datapipeline import IOHandler
+
+# 加载H5数据
+data = IOHandler.load_h5("./cached_data")
 ```
