+### Slug Configuration
+
+By default, slugs are generated from the filepath (e.g., `posts/my-post.md` becomes `posts/my-post`). To use a frontmatter field instead:
+
+```json
+{
+  "frontmatter": {
+    "slugField": "url"
+  }
+}
+```
+
+If the frontmatter field is not found, it falls back to the filepath.
+
 ### Ignoring Files
 
 Some frameworks use special files like `_index.md` (Zola) for section pages that aren't actual blog posts. Use the `ignore` field to skip these files during publishing:
