+- Introduce a custom configuration called `tolerateRepublish` which supports running
+  npm publish with the flag `--tolerateRepublish`. This flag allows you to publish 
+  on top of an existing npm package. 
+
+  To turn on this flag, update your generators.yml: 
+
+  ```yaml
+  groups: 
+    generators: 
+      - name: fernapi/fern-typscript-node-sdk
+        version: 0.12.5
+        ...

 - Fix: Previously reference.md was just leveraging the function name for the reference, now it leverages the full package-scoped path, mirroring how the function would be used in reality.
