</head>Custom Usage
For baseline social share functionality, providing arguments shown in the example usage above is recommended. If you want to add more tags not listed in the example, have a look at the plugin docs. You might only need a few <meta> tags instead of the whole set, simply provide the arguments you need and the ones not included won't generate <meta> tags.
Template variables can be used as arguments in Nunjucks and Liquid without the curly braces or quotes like title=page.url. See the metagen docs for more details on plugin usage.
Use Your Template Data
To make your metadata dynamic, you can use template data as arguments to the shortcode, without quotes or braces:
---
title: Some title
desc: Some description
metadata:
title: Some other title
desc: Some other description
url: https://tannerdolby.com
