# Ignoring Files
This document provides an overview of the Gemini Ignore (`.geminiignore`) feature of the Gemini CLI.
The Gemini CLI includes the ability to automatically ignore files, similar to `.gitignore` (used by Git) and `.aiexclude` (used by Gemini Code Assist). Adding paths to your `.geminiignore` file will exclude them from tools that support this feature, although they will still be visible to other services (such as Git).
## How it works
When you add a path to your `.geminiignore` file, tools that respect this file will exclude matching files and directories from their operations. For example, when you use the [`read_many_files`](./tools/multi-file.md) command, any paths in your `.geminiignore` file will be automatically excluded.
For the most part, `.geminiignore` follows the conventions of `.gitignore` files:
- Blank lines and lines starting with `#` are ignored.
- Standard glob patterns are supported (such as `*`, `?`, and `[]`).
- Putting a `/` at the end will only match directories.
- Putting a `/` at the beginning anchors the path relative to the `.geminiignore` file.
- `!` negates a pattern.
You can update your `.geminiignore` file at any time. To apply the changes, you must restart your Gemini CLI session.
## How to use `.geminiignore`
To enable `.geminiignore`:
1. Create a file named `.geminiignore` in the root of your project directory.
To add a file or directory to `.geminiignore`:
1. Open your `.geminiignore` file.
2. Add the path or file you want to ignore, for example: `/archive/` or `apikeys.txt`.
### `.geminiignore` examples
You can use `.geminiignore` to ignore directories and files:
```
# Exclude your /packages/ directory and all subdirectories
/packages/
# Exclude your apikeys.txt file
apikeys.txt
```
You can use wildcards in your `.geminiignore` file with `*`:
```
# Exclude all .md files
*.md
```
Finally, you can exclude files and directories from exclusion with `!`:
```
# Exclude all .md files except README.md
*.md
!README.md
```
To remove paths from your `.geminiignore` file, delete the relevant lines.
