# 404
***
The **404 page** includes a simple layout that displays a 404 message "**Page not found**" and a button to redirect customers back to the home page.
You do not need to set up a 404 page - it shows by default - but you can choose to add custom theme sections and edit the default theme content.
### How to edit 404 page?
To keep customers shopping, you may want to add some custom theme sections, such as a featured collection or a collection list.
**STEPS**
* In your theme editor, use the **Templates selector** to open **Others > 404 page**.
* Add and edit theme sections (link article: Sections) to customize the layout of your page.
* Click **Save**.
