# Context:
USER: give inputoutput defaults of pretty=true and yes=false
ASSISTANT: To update the default values of `pretty` and `yes` in the `InputOutput` class, I will modify the `__init__` method in the `io.py` file.
```python
aider/io.py
<<<<<<< ORIGINAL
def __init__(self, pretty, yes, input_history_file=None, chat_history_file=None, input=None, output=None):
=======
def __init__(self, pretty=True, yes=False, input_history_file=None, chat_history_file=None, input=None, output=None):
>>>>>>> UPDATED
```
# Context:
USER: add missing commands to the Chat commands section
ASSISTANT: I will add the missing commands to the Chat commands section in the README.md file.
```markdown
README.md
<<<<<<< ORIGINAL
`aider` supports the following commands from within the chat:
* `/add <file>`: Add matching files to the chat session.
* `/drop <file>`: Remove matching files from the chat session.
* `/ls`: List all known files and those included in the chat session.
* `/commit [message]`: Commit outstanding changes to the chat session files. Use this to commit edits you made outside the chat, with your editor or git commands. aider will provide a commit message if you don't.
* `/undo`: Undo the last git commit if it was done by aider.
* `/diff`: Display the diff of the last aider commit.
