# Auto-run

Activating Reader Mode's distraction-free reader manually every time can be tiresome, especially when visiting the same websites frequently. That's where an Auto-run feature for Reader Mode comes in.

An Auto-run feature for Reader Mode allows the user to specify websites where Reader Mode should activate automatically, using a [regular expression (regex)](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Regular_Expressions) pattern. Regex patterns are powerful tools for matching text, and they can be used to match website URLs too. The user can specify a regex pattern that matches the URLs of the websites they want Reader Mode to activate on automatically.

For example, let's say you frequently read articles on a blog with a URL like *<https://example.com/blog/post/123>*. You could create a regex pattern like `^https://example.com/blog/` to match all URLs that start with *<https://example.com/blog/>*. Or you can create a regex pattern such as `/bbc.co.uk\/news/` to match all URLs that contains *bbc.co.uk/news*. Then, you could pu these patterns on the Auto-run feature settings for Reader Mode to activate on all URLs that match these patterns.
