# Favicon

When there is a `favicon.*` file in the `config` directory at the root of the project, Modern.js will automatically set the file to the [html.favicon](/configure/app/html/favicon.md) configuration option for generating the favicon icon on the page:

```
./config
└── favicon.ico
```

After the build is completed, you can see the following tags automatically generated in HTML:

```html
<link rel="icon" href="/favicon.ico" />
```

## Order

When setting up the favicon, Modern.js looks for files in the following order:

- `favicon.png`
- `favicon.jpg`
- `favicon.jpeg`
- `favicon.svg`
- `favicon.ico`
