+# Label Aliases
+
+When there are more than one issue associated with a particular label, GitReleaseManager will attempt to pluralize the label name.  For example, `Bugs` instead of `Bug`.  However, there are times when this basic pluralization will not work.  For example, `Documentation` will be pluralized as `Documentations` which doesn't really make sense.  In these situations, it is possible to override the automatic title.
+
+This is possible for both the singular and plural cases.
+
+Here is an example of how to configure two label aliases.  The title `Foo` will be used instead of `Bug`, and `Baz` instead of `Improvement`.  If each label contains more than one feature, `Bar` and `Qux` will be used instead in the release notes.
+
+```
+issue-labels-alias:
+    - name:    Bug
+      header:  Foo
+      plural:  Bar
+
+    - name:    Improvement
+      header:  Baz
+      plural:  Qux
+```

+        You can add as many label aliases as required.
