 ### Ignoring Files
 
-By default, your `.git` directory and your `.gitignore` and `LICENSE` files are ignored. If you want to change this behavior, you should add a `.gptignore` file to your repository. The `.gptignore` file should contain a list of files and directories to ignore, one per line. The `.gptignore` file should be in the same directory as your `.gitignore` file. Please note that this overwrites the default ignore list, so you should include the default ignore list in your `.gptignore` file if you want to keep it.
