 ## Customize configurations
 
-You can customize the configurations for your own task and agent by directly pass the absolute path of the configuration file to `get_config` function. For example, if you want to customize the configurations for `DoughRolling` task, you can create a `DoughRolling.yaml` file in `[path]/task` and pass the absolute path of the file to `get_config` function. Then, you can customize the configurations for `PPO` algorithm by creating a `DoughRollingPPO.yaml` file in `[path]/train` and pass the absolute path of the file to `get_config` function. Remember to copy the `config` file to your own `[path]`.
