+## Metrics
+
+This book uses the [Goal-Question-Metric] approach to documenting InnerSource metrics.
+[Goals], [questions], and [metrics] are kept in separate files with markdown links between them indicating which are related to one other.
+The full graph of relationships is visible in this [graph](https://github.com/InnerSourceCommons/managing-inner-source-projects/blob/master/measuring/use_gqm.md).
+
+Add in your scenarios by copying this [goal template], [question template], and/or [metric template], filling them out, and submitting them in pull request.
+By adding in your scenarios to the graph, you will be able to see how others approach and interact with them.
+You may get new ideas of what metrics answer the questions you have or what additional goals your questions can support.
+
 ## Guidelines
 
 When using titles in Markdown, use # for main title, ## for the second header title, etc. It's just to follow the same style :).
