+
+The Relearn theme supports Hugo's default taxonomies *tag* and *category* out of the box.
+
+## Configuration
+
+Just add tags and/or categories to any page. They can be given as a single string or an array of strings.
+
+```toml
++++
+categories = ["taxonomy", "content"]
+tags = "tutorial"
+title = "Taxonomy"
++++
+```
+
+## Behavior
+
+The tags are displayed at the top of the page in alphabetical order.
+
+The categories are displayed at the bottom of the page in alphabetical order in the default implementation of the theme but can be customized by providing your own `content-footer.html` partial.
+
+Each item is a link to a taxonomy page displaying all the articles with the given term.
+
+## List all the tags
+
+In the `config.toml`  file you can add a shortcut to display all the tags and categories
+
+```toml
+[[menu.shortcuts]]
+name = "<i class='fas fa-tags'></i> Tags"
+url = "/tags"
+
+[[menu.shortcuts]]
+name = "<i class='fas fa-list'></i> Categories"
+url = "/categories"
+```
