 | `name`   | e.g. `"stockfish"`                | Name of executable of the engine, e.g. `stockfish`. Unfortunately this name must be precisely equal to the name of the json file, and must be referenced in `preferences.json` as either `computer_player_name` or `computer_player2_name` and within `active_agents`. That is subject to improvement in the future. |
 | `path`   | e.g. `"/usr/local/bin/stockfish"` | Path to the engine executable. Windows users must either use `\\` or `/` in json files as path separators.                                                                                                                                                                                                           |

 Once the UCI engine is started for the first time, the UCI-options of the engine are enumerated and added to the `<engine-name>.json` config file. That allows further customization of each engine. Some commonly used options are:
