 For adding your own rule you should create `your-rule-name.py`
-in `~/.thefuck/rules`. Rule should contain two functions:
-`match(command: Command, settings: Settings) -> bool`
-and `get_new_command(command: Command, settings: Settings) -> str`.

+`side_effect(command: Command, settings: Settings) -> None` and an
 optional boolean `enabled_by_default`.
 
 `Command` has three attributes: `script`, `stdout` and `stderr`.
