 3. Optionally, install [universal ctags](https://github.com/universal-ctags/ctags). This is helpful if you plan to use aider and GPT-4 with repositories that have more than a handful of files.  This allows aider to build a [map of your entire git repo](https://aider.chat/docs/ctags.html) and share it with GPT to help it better understand and modify large codebases.
   * The `ctags` command needs to be on your shell path so that it will run by default when aider invokes `ctags ...`.
