 Trinity-RFT provides a modular development approach, allowing you to flexibly add custom modules without modifying the framework code.
 You can place your module code in the `trinity/plugins` directory. Trinity-RFT will automatically load all Python files in that directory at runtime and register the custom modules within them.
 Trinity-RFT also supports specifying other directories at runtime by setting the `--plugin-dir` option, for example: `trinity run --config <config_file> --plugin-dir <your_plugin_dir>`.
+Alternatively, you can use the relative path to the custom module in the YAML configuration file, for example: `default_workflow_type: 'examples.agentscope_frozenlake.workflow.FrozenLakeWorkflow'`.
 ```
 
 For modules you plan to contribute to Trinity-RFT, please follow these steps:
 
 1. Implement your code in the appropriate directory, such as `trinity/common/workflows` for `Workflow`, `trinity/algorithm` for `Algorithm`, and `trinity/buffer/operators` for `Operator`.
 
-2. Register your module in the corresponding `__init__.py` file of the directory.
