          ## 📦 安装

          ### pip 安装
          ```bash
          pip install base-model-trpgner
          ```

          ### 使用 uv（推荐）
          ```bash
          uv pip install base-model-trpgner
          ```

          ### 训练模式
          ```bash
          pip install base-model-trpgner[train]
          ```

          ## 🚀 快速开始
          ```python
          from base_model_trpgner import TRPGParser

          parser = TRPGParser()
          result = parser.parse("风雨 2024-06-08 21:44:59 剧烈的疼痛...")
          print(result)
