 ## Monitoring the Training Process
 
-We recommend using Weights & Biases (wandb) for monitoring. Run `wandb login` or set the `WANDB_API_KEY` environment variable. Set `wandb.mode=online` in your configuration to upload training statistics.
++ We recommend using [Weights & Biases (wandb)](https://github.com/wandb/wandb)  or [SwanLab](https://github.com/SwanHubX/SwanLab)  for monitoring—run `wandb login` or `swanlab login`, or set the corresponding environment variable API key (`WANDB_API_KEY` or `SWANLAB_API_KEY`). Set `wandb.mode="online"` or `swanlab.mode="cloud"` in your configuration to upload training statistics. If you cannot connect to the server, you can also use `wandb.mode="offline"` or `swanlab.mode="local"` to save data locally without uploading.
+
 
 You can also use TensorBoard by setting the `tensorboard.path` parameter.
 
 The main log will be saved to `${fileroot}/logs/${USER}/${experiment_name}/${trial_name}/main.log` and contains the statistics uploaded to wandb.
 
+If SwanLab is enabled, logs will be saved to the directory specified by `swanlab.logdir`.

 ### Key Training Statistics
 
 - **`Epoch 1/5`**: Indicates the total epochs required and the current epoch being trained.
