Jekyll include file for navbar.
Copy file navigation.md to your site's _includes/ directory. You must have defined those variables in _config.yml:
navigation:
- your pages you want to add to navbar here in list; Example:
- absolute/path/to/my-page1.md # Please specify absoulte path or with domain name
If your domain isn't served at GitHub Pages, specify such mapping in _config.yml too:
domain_name: https://example.com
You can simply type {% include navigation.html current=page.url %}
Vóila!
