+Save that config in a `.yaml` and get started immediately! An example CLI config is available as `examples/cli_configs/example_config.yaml`. Note you can overwrite the arguments from the config file by explicitly passing them to the CLI, e.g. from the root folder:
 
 ```bash
-trl sft --config example_config.yaml --output_dir test-trl-cli --lr_scheduler_type cosine_with_restarts
+trl sft --config examples/cli_configs/example_config.yaml --output_dir test-trl-cli --lr_scheduler_type cosine_with_restarts
 ```
 
 Will force-use `cosine_with_restarts` for `lr_scheduler_type`.
