 Title and description (excerpt) are important for search engine optimization (SEO) and thus AstroPaper encourages to include these in blog posts.
 
-`slug` is the unique identifier of the url. Thus, `slug` must be unique and different from other posts. The whitespace of `slug` needs to be separated with `-` or `_` but `-` is recommended. However, even if you don't write the correct slug, AstroPaper will automatically slugify your incorrect slug. If slug is not specified, the slugified title of the post will be used as slug.
+`slug` is the unique identifier of the url. Thus, `slug` must be unique and different from other posts. The whitespace of `slug` should to be separated with `-` or `_` but `-` is recommended. Slug is automatically generated using the blog post file name. However, you can define your `slug` as a frontmatter in your blog post.
+
+For example, if the blog file name is `adding-new-post.md` and you don't specify the slug in your frontmatter, Astro will automatically create a slug for the blog post using the file name. Thus, the slug will be `adding-new-post`. But if you specify the `slug` in the frontmatter, this will override the default slug. You can read more about this in [Astro Docs](https://docs.astro.build/en/guides/content-collections/#defining-custom-slugs).
 
 If you omit `tags` in a blog post (in other words, if no tag is specified), the default tag `others` will be used as a tag for that post. You can set the default tag in the `/src/content/config.ts` file.
