+### Embedding SVG metrics
+
+You can also generate "on-the-fly" SVGs metrics image using the `embed` function:

+<%- await embed({isocalendar:true, isocalendar_duration:"full-year"}) %>
+
+Available configuration options are mostly the same as [action.yml](https://github.com/lowlighter/metrics/blob/master/action.yml). Note that tokens options must **not** be passed to this function. These will be automatically passed down when defined in your workflow job.
