 - `ROS_DOMAIN_ID` **(Required)**: which is used to define nodes that should be able to see each other. In our [ROS2 nodes](getting_started_controllers.md) they are set to 100 as default.
 - `CRISP_CONFIG_PATH` **(Optional)**: which should be the path to a config folder similar to [config path of CRISP_PY](https://github.com/utiasDSL/crisp_py/tree/main/config) or [config path of CRISP_GYM](https://github.com/utiasDSL/crisp_gym/tree/main/crisp_gym/config) but with your own custom configurations.

 1. This will avoid downloading large files when cloning the repository. You can always download them later with `git lfs pull`.
 2. This will remove logging from SVT codecs, which are used to create data in LeRobot format. The logs can be quite verbose.

 !!! WARNING "Note on LeRobotDataset version"
     Take a look at the `pixi.toml`. You can define your `lerobot` version there.
     If you want to use later LeRobotDataset v3.0, you need to remove the `rerun` dependency/downgrade it in the `lerobot` like it is done [here](https://github.com/danielsanjosepro/lerobot/commit/b7aea681cda32eee21fa2b368af2119596f4e3ea) since it requires `numpy>=2.0` which is not compatible with the ROS2 versions of `numpy`.
     This will require a small change in the `pixi.toml`:
     ```toml title="pixi.toml" hl_lines="11-12"
