-## Duplicated code
+## Duplicated Code
 
 Duplicated code can lead to software that is hard to understand and difficult to change. The Don't Repeat Yourself (DRY) principle states:
 
 > Every piece of knowledge must have a single, unambiguous, authoritative representation within a system.
 
 When you violate DRY, bugs and maintenance problems are sure to follow. Duplicated code has a tendency to both continue to replicate and also to diverge (leaving bugs as two similar implementations differ in subtle ways).
 
+## Issue Mass
+
+Duplicated code has a calculated mass, which can be thought of as a measure of how much logic has been duplicated.
+This issue has a mass of `<%= issue.mass %>`: if you would like to change the minimum mass that will be reported as an issue, please see the details in [`codeclimate-duplication`'s documentation](https://github.com/codeclimate/codeclimate-duplication).
