+
+To apply [Front Matter defaults](https://jekyllrb.com/docs/configuration/front-matter-defaults/) to pages generated by the `jekyll-archives` plugin, you can specify a scope of an empty `path` and a `type` of either `tag` or `category`.
+
+For example, the following configuration enables author profile on tag archives and disables comments on category archives.
+
+```yaml
+defaults:
+  - scope:
+      path: ""
+      type: tag
+    values:
+      author_profile: true
+  - scope:
+      path: ""
+      type: category
+    values:
+      comments: false
+```

 ## HTML compression
 
 If you care at all about performance (and really who doesn't) compressing the HTML files generated by Jekyll is a good thing to do.
