 ### Other features
 
+#### GitHub repositories and user stats
+**al-folio** uses [github-readme-stats](https://github.com/anuraghazra/github-readme-stats) to display GitHub repositories and user stats on the the `/repositories/` page.
+
+Edit the `_data/repositories.yml` and change the `github_users` and `github_repos` lists to include your own GitHub profile and repositories to the the `/repositories/` page.
+
+You may also use the following codes for displaying this in any other pages.
+```
+<!-- code for GitHub users -->
+{% if site.data.repositories.github_users %}
+<div class="repositories d-flex flex-wrap flex-md-row flex-column justify-content-between align-items-center">
+  {% for user in site.data.repositories.github_users %}
+    {% include repository/repo_user.html username=user %}
+  {% endfor %}
+</div>
+{% endif %}

 #### Theming
 Six beautiful theme colors have been selected to choose from.
 The default is purple, but you can quickly change it by editing `$theme-color` variable in the `_sass/_themes.scss` file.
