## About

Aider is a terminal-based AI coding assistant that edits project files with model assistance and uses repository context to guide changes.

## Key Features

- Work on code, configuration and documentation through a conversation.
- Use a repository map to provide structural context about the codebase.

## Use Cases

Read project context, make code changes and review the results in a coding-agent workflow.

## Setup or Requirements

Install with `python -m pip install aider-install`, then run `aider-install`. Open the intended repository and launch `aider` with the model provider configuration from the official guide. Provider credentials and usage costs depend on that selection.

## Limitations

The repository map is a built-in context feature. File edits and Git operations apply to the project you open.
