# Footnotes

Footnotes can help add descriptive information for a name, a term, or a phrase in the text. In Setka Editor, they appear in a modern way — as popovers.

## Adding a Footnote

To add a footnote, select a text and click the **Footnote** button in Upper Contextual Toolbar.

When you click the **Footnote** button, the popup window will open. There you can add various content (text, images, embeds, icons, dividers). Elements inside footnotes can be further designed by changing indents, colors, etc. By default the text format “Small text” is applied to all the footnotes content. However, you can change that.

## Editing Footnote Settings

You can set the way the footnote appears in the post (on the page) when it's published. Change **Footnote** setting in the Upper Contextual Toolbar. For desktop, you can choose mouseover or click. Оn mobile devices popover footnotes open with a touch event.‌
