 This document outlines how to customize the build output through Helm overrides and `package.json` configurations.
 
+## Display Node Warnings
+
+You can display warnings in the logs by setting the `PEPR_NODE_WARNINGS` environment variable to `true` in the `package.json` file or directly on the Watcher or Admission `Deployment`. The default value is `undefined`.
+
+```json
+{
+  "env": {
+    "PEPR_NODE_WARNINGS": "true"
+  }
+}
+```
+
 ## Customizing Log Format
 
 The log format can be customized by setting the `PINO_TIME_STAMP` environment variable in the `package.json` file or directly on the Watcher or Admission `Deployment`. The default value is a partial JSON timestamp string representation of the time. If set to `iso`, the timestamp is displayed in an ISO format.

 ## How do I remove the punycode warning?
 
+By default, warnings are removed. You can allow warnings by setting the `PEPR_NODE_WARNINGS` environment variable.
+
+```bash
+PEPR_NODE_WARNINGS="true"
+```
+
+If you allow warnings, you can disable the specific punycode warning by:

 ```bash
 export NODE_OPTIONS="--disable-warning=DEP0040"

 ## How does Pepr compare to Operator SDK?
 
 Pepr and Operator SDK are both frameworks used for building Kubernetes operators and admission controllers. While they share a common goal of simplifying the creation of Kubernetes operators and enhancing Kubernetes functionality, they have different approaches and features.
