# slugify

Created by [@Divlo](https://github.com/Divlo) on 10 November 2021.

## Instructions

A Slug is the unique identifying part of a web address, typically at the end of the URL.

The rules for generating a slug are as follows (`kebab-case`):

- Replace spaces with hyphens.
- Remove all non-alphanumeric characters.
