 ## Step 2. Review the Cookbook and Customize Development
 
-We strongly recommend that developers review our [cookbook](https://github.com/modelscope/twinkle/tree/main/cookbook/client/) and build upon the training code provided there.

+> The ModelScope server is tinker-compatible, so use the tinker cookbooks. In the future version, we will support a server works both for twinkle/tinker clients.
 
 Developers can customize datasets, advantage functions, rewards, templates, and more. However, the Loss component is not currently customizable since it needs to be executed on the server side (for security reasons). If you need support for additional Loss functions, you can upload your Loss implementation to ModelHub and contact us via the Q&A group or through an issue to have the corresponding component added to the whitelist.

 ## Step 2. 查看 Cookbook 并二次定制开发

 开发者可以定制数据集/优势函数/奖励/模板等，其中 Loss 部分由于需要在服务端执行，因此当前暂不支持（安全性原因）。
 如果需要支持您的额外 Loss，可以将该 Loss 实现上传到 ModelHub 中，并在答疑群中或者 issue 中联系我们，将对应组件开放白名单即可使用。
