# Logo

For best results with GrainBits, **use a square-shaped image** for your logo. The theme will automatically display it with clean proportions throughout your site.

To upload your logo:

1. In the Ghost Admin, go to `Settings`, navigate to `Design & branding`, and click on `Customize`.

<figure><img src="/files/ymscS1Owk302GmnQEYsr" alt=""><figcaption></figcaption></figure>

2. Locate "Publication logo" and select `Upload logo`, or drag and drop your image into the upload area.

<figure><img src="/files/jIa9fXzXldCDzDFwwUzD" alt=""><figcaption></figcaption></figure>
