 If you would like to change the code, we recommend you to use the Jupyter Notebook to open these markdown files as described in :numref:`sec_jupyter`. So that you can run and test your changes. Please remember to clear all outputs before submitting your changes, our CI system will execute the sections you updated to generate outputs.
 
 Some sections may support multiple framework implementations.
-If you add a new code block not for the default implementation, which is MXNet, please use `#@tab` to mark this block on the beginning line. For example, `#@tab pytorch` for a PyTorch code block, `#@tab tensorflow` for a TensorFlow code block, or `#@tab all` a shared code block for all implementations. You may refer to the [`d2lbook`](http://book.d2l.ai/user/code_tabs.html) package for more information.
